Moment to Moment
And also for me stays unclear how to change locale using es6? Is it possible with latest version of this library? Most of the functions are methods of the moment object. See Skip to content.

Returns a machine readable string, that can be evaluated to produce the same moment. Because of the name its also used in node interactive shell to display objects. Note: This function is mostly intended for debugging, not all cases are handled precisely. Check if a moment is before another moment.
The first argument will be parsed as a moment, if not already so. If you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter. As the second parameter determines the precision, and not just a single value to check, using day will check for year, month and day. Like moment isAfter and moment isSame , any of the units of time that are supported for moment startOf are supported for moment isBefore.
NOTE : moment. If the code runs fast the initial created moment would be the same as the one created in isBefore to perform the check, so the result would be false. But if the code runs slower it's possible that the moment created in isBefore is measurably after the one created in moment , so the call would return true.

Moment By Moment
If you want to limit the granularity to a unit other than milliseconds, pass it as the second parameter. When including a second parameter, it will match all units equal or larger. Passing in month will check month and year. Passing in day will check day , month , and year. Like moment isAfter and moment isBefore , any of the units of time that are supported for moment startOf are supported for moment isSame. If the two moments have different timezones, the timezone of the first moment will be used for the comparison.
If the code runs fast the initial created moment would be the same as the one created in isSame to perform the check, so the result would be true. But if the code runs slower it's possible that the moment created in isSame is measurably after the one created in moment , so the call would return false. Check if a moment is after another moment.
Like moment isSame and moment isBefore , any of the units of time that are supported for moment startOf are supported for moment isAfter. Check if a moment is before or the same as another moment. Like moment isAfter and moment isSame , any of the units of time that are supported for moment startOf are supported for moment isSameOrBefore :. Check if a moment is after or the same as another moment. Like moment isSame and moment isBefore , any of the units of time that are supported for moment startOf are supported for moment isSameOrAfter :.
Check if a moment is between two other moments, optionally looking at unit scale minutes, hours, days, etc. The match is exclusive. The first two arguments will be parsed as moments, if not already so. If you want to limit the granularity to a unit other than milliseconds, pass the units as the third parameter. Like moment isSame , moment isBefore , moment isAfter any of the units of time that are supported for moment startOf are supported for moment isBetween.
Year, month, week, isoWeek, day, hour, minute, and second. Version 2. A [ indicates inclusion of a value. A indicates exclusion. If the inclusivity parameter is used, both indicators must be passed. Note that in the event that the from and to parameters are the same, but the inclusivity parameters are different, false will preside.
Note: As of version 2. It doesn't give the right answer after modifying the moment object. Another important piece of validation is to know if the date has been moved by a DST. For example, in most of the United States:. This is because daylight saving time shifts the time from to , so isn't a real time. The resulting time is browser-dependent, either adjusting the time forward or backwards.
Use moment isDSTShifted to test for this condition. Note: before 2. By default, Moment. If you need other locales, you can load them into Moment. More details on each of the parts of the locale bundle can be found in the customization section.

Details about week. Once you load a locale, it becomes the active locale. To change active locales, simply call moment. This is useful because Moment won't change locales if it doesn't know the one you specify. You may also specify a list of locales, and Moment will use the first one it has localizations for.
Moment will also try locale specifier substrings from most-specific to least-specific until it finds a locale it knows. This is useful when supplying Moment with a locale string pulled from the user's environment, such as window. A global locale configuration can be problematic when passing around moments that may need to be formatted into different locale. If you call moment locale with no parameters, you get back the locale configuration that would be used for that moment. It works the same way it does in the global locale configuration. Loading locales in NodeJS is super easy.
If you want your locale supported, create a pull request to the develop branch with the required locale and unit test files. Loading locales in the browser just requires you to include the locale files. Be sure to specify the charset to prevent encoding issues. Note: Locale files are defined in UMD style, so they should work seamlessly in all environments. To add your locale to Moment. If you are changing locales frequently, you may want to know what locale is currently being used.
This is as simple as calling moment. It is sometimes useful to get the list of months or weekdays in a locale, for example when populating a dropdown menu. Similarly, moment. If true, the weekdays will be returned in locale specific order.
For instance, in the Arabic locale, Saturday is the first day of the week, thus:. Note: Absent the locale specific parameter, weekdays always have Sunday as index 0, regardless of the local first day of the week. Some locales make special considerations into account when formatting month names.
For example, Dutch formats month abbreviations without a trailing period, but only if it's formatting the month between dashes. The months method supports passing a format in so that the months will be listed in the proper context. You can access the properties of the currently loaded locale through the moment.
Moment to Moment - Wikipedia
It returns the current locale or a locale with the given key:. Details about firstDayOfYear can be found in the customization section. This locale will populate the dates with very obviously changed data. Pseudo locales can be useful when testing, as they make obvious what data has and has not been localized.
Just include the pseudo-locale, and set moment's locale to x-pseudo. Text from Moment will be very easy to spot. In general, you should create a locale setting with your customizations. You can remove a previously defined locale by passing null as the second argument. The deleted locale will no longer be available for use.
Failing that it will default the parent to the global locale. Any properties specified will be updated, while others will remain the same. This function does not affect moments that already exist. If you need more processing to calculate the name of the month, for example, if there is different grammar for different formats , Locale months can be a function with the following signature. It should always return a month name. Like Locale months , Locale monthsShort can be a callback function as well.
Locale weekdaysMin should be an array of two letter weekday abbreviations. The purpose of these is for things like calendar pickers, thus they should be as small as possible. LT should be the time format, and is also used for moment calendar. You can eliminate the lowercase l tokens and they will be created automatically by replacing long tokens with the short token variants.
Locale relativeTime should be an object of the replacement strings for moment from. Locale relativeTime. For all others, a single character refers to the singular, and a double character refers to the plural. If a locale requires additional processing for a token, it can set the token as a function with the following signature. The function should return a string. The key argument refers to the replacement key in the Locale relativeTime object.
The number argument refers to the number of units for that key. For m , the number is the number of minutes, etc. The withoutSuffix argument will be true if the token will be displayed without a suffix, and false if it will be displayed with a suffix. The reason for the inverted logic is because the default behavior is to display with the suffix.
Locale isPM should return true if the input string is past 12 noon. This is used in parsing the a A tokens. To configure what strings should be parsed as input, set the meridiemParse property. Each of the Locale calendar keys can also be a callback function with the scope of the current moment and first argument a moment that depicts now. It should return a formatting string. Previously, only the ordinal was returned. It is a string of the token that is being ordinalized, for example: M or d. For more information on ordinal numbers, see Wikipedia.
For example, by default more than 45 seconds is considered a minute, more than 22 hours is considered a day and so on. To change those cutoffs use moment. Note: Retrieving and setting ss threshold was added in 2. To control the rounding you can use moment. If you want to change the time that Moment sees, you can specify a method that returns the number of milliseconds since the Unix epoch January 1, This will be used when calling moment , and the current date used when tokens are omitted from format.
In general, any method that needs the current time uses this under the hood. Locale week. Where a moment is defined as single points in time, durations are defined as a length of time. A duration is conceptually more similar to '2 hours' than to 'between 2 and 4 pm today'.
As such, they are not a good solution to converting between units that depend on context. For example, a year can be defined as days, days, Trying to convert years to days makes no sense without context. It is much better to use moment diff for calculating days or years between two moments than to use Durations. To create a duration, call moment. If you want to create a moment with a unit of measurement other than milliseconds, you can pass the unit of measurement as well.
The same shorthand for moment add and moment subtract works here as well. Much like moment add , you can pass an object of values if you need multiple different units of measurement. NET style time spans. The following formats are supported. The format is an hour, minute, second string separated by colons like The number of days can be prefixed with a dot separator like so 7.
Partial seconds are supported as well To create an invalid duration you can pass NaN for a value of a unit. Create a clone of a duration. Durations are mutable, just like moment objects, so this lets you get a snapshot, at some point in time. Sometimes, you want all the goodness of moment from but you don't want to have to create two moments, you just want to display a length of time. To get the number of milliseconds in a duration, use moment. If you want the length of the duration in milliseconds, use moment. If you want the length of the duration in seconds, use moment.
As with the other getters for durations, moment. Pay attention that unlike the other getters for duration, weeks are counted as a subset of the days, and are not taken off the days count. You can also use duration with moment diff to get the duration between two moments. To do so, simply pass the moment diff method into moment duration as follows:.
See here for more information about moment diff. As an alternate to Duration asX , you can use Duration as 'x'. All the shorthand keys from moment add apply here as well. As an alternate to Duration x getters, you can use Duration get 'x'. Returns duration in string as specified by ISO standard. You can get or set the locale of a duration using locale The locale will affect the duration's string methods, like humanize.
See the intl section for more information on internationalization generally. Moment exposes some methods which may be useful to people extending the library or writing custom parsers. Many of Moment's functions allow the caller to pass in aliases for unit enums. For example, all of the get s below are equivalent. If you're extending the library, you may want access to Moment's facilities for that in order to better align your functionality with Moment's. This will not set the userInvalidated parsing flag unless it's one of the properties specified.
Another range plugin is Isaac Cambron's library Twix. It has many range-related features and excels at formatting ranges readably. Full documentation of all the options and features is here. Or just grab the JS file from here. To obtain the raw numeric values rather than a string, pass the value true as the third argument to the method:.
When installed, it will wrap moment and moment will be able to format and parse Jalaali years and months. Here is a short example:. If you want to work with Hijri calendar then you can use moment-hijri plugin. This plugin is developed by Suhail Alkowaileet. When you install it, it will wrap moment and you will be able to parse Hijri dates. If you need to work with recurring dates, you can use Casey Trimm's plugin moment-recur. This plugin will allow you to create length-based intervals days, weeks, etc.

It provides a matches function to test whether a date recurs according to the rules set, as well as generator functions to get the next and previous dates in a series. The repository, documentation, and many more examples can be found at github. If you're trying to format times for tweets like the way Twitter does, you can use the moment.
If you ever have need for Fiscal , Calendar or Academic quarters, you can use the moment-fquarter plugin by robgallen. At its simplest, just call the fquarter method on any moment object. It returns a formatted string with April being the first quarter. Find an example usage of it at minutes. The Plugin has been authored by gr2m. Links: Demo Source. Optional parameters lets you specify custom patterns and force strict pattern usage non-alphabetic characters are not mandatory in passed string by default. You can see it live there while the repository is here. If you want to work with Taiwan calendar system , you can use Bradwoo's plugin moment-taiwan.
Holidays are taken from Wikipedia de. It's a bit complicated to determine if a date is a holiday, because religious holidays vary every year and differ within the 16 German states. Moment Moment Timezone Luxon. Search the docs. Where to use it Node. Utilities Normalize Units Invalid. Where to use it Moment was designed to work both in the browser and in Node. If you want to try the sample codes below, just open your browser's console and enter them.
If you are having any troubles, the first place to check is the guides. Please read: moment Ambiguous input without offset is assumed to be local time. Unambiguous input with offset is adjusted to local time. Ambiguous input is assumed to be UTC. Unambiguous input is adjusted to UTC. If the input is ambiguous, it is the same as local mode.
These map to the corresponding function on the native Date object. Note: All of these methods mutate the original moment when used as setters.
Once parsing and manipulation are done, you need some way to display the moment. You can load multiple locales and easily switch between them. In addition to assigning a global locale, you can assign a locale to a specific moment. To run the tests in Node. If all the tests pass, submit a pull request, and thank you for contributing! To revert an update use: moment.
Durations do not have a defined beginning and end date. They are contextless.
