m. refers to an instance of moment().- Amounts can be overloaded, eg:
.hour(48) is 2 days, .day(-7) is last Sunday
- When chaining, set year, then month, then day, etc. Otherwise dates may overload in unexpected ways.
- Moment parses and displays in local time by default. Use
m.utc() to set to UTC mode, and m.local() to switch back.
- All moments are mutable. Use
m.clone() or moment(m)
- For code accepting
m2, it (usually) also supports anything that can be parsed (eg: string, object, array, date, etc)
- For strict parsing (recommended), pass
true as the final param
- Omitted units default to 0 for current date, month, and year.
moment("12-25-1995"); // ISO 8601, or falls back to JS `Date.parse()` which differs between browser implementation
moment("12-25-1995", "MM-DD-YYYY"); // Format tokens: http://momentjs.com/docs/#/parsing/string-format/
moment({ hour:15, minute:10 });
moment({ y :2010, M :3, d :5, h :15, m :10, s :3, ms :123});
moment({ year :2010, month :3, day :5, hour :15, minute :10, second :3, millisecond :123});
moment({ years:2010, months:3, days:5, hours:15, minutes:10, seconds:3, milliseconds:123});
moment({ years:2010, months:3, date:5, hours:15, minutes:10, seconds:3, milliseconds:123});
// `day` and `date` both mean day-of-the-month.
moment([year, month, day, hour, minute, second, millisecond]);
moment([2010]); // January 1st
moment([2010, 6]); // July 1st
moment([2010, 6, 10]); // July 10th
moment(unixTimestampMilliseconds)
moment(new Date());
moment(momentInstance);
moment("not a real date"); // false
m.isValid(); // false
m.parsingFlags(); // more details
- Act as 'getter' when called without a parameter
- Functions work as both singular and plural (only singular shown below)

// The following work in the same way:

m.isAfter();
m.isSameOrBefore();
m.isSameOrAfter();
m.isBetween(m1, m2);
m.isBetween(m1, m2, 'year');
m.isBetween(m1, m2, null, '[)'); // `[` or `]` = inclusive, `(` or `)` = exclusive, `()` by default

m.isLeapYear()
m.max(m2[, m3...]); // Returns m instance
m.max(m[]); // Returns m instance
m.min(m2[,m3...]); // Returns m instance
m.min(m[]); // Returns m instance
- Lengths of time
- No defined beginning or end date
- Eg: '2 hours' or 'Between 2pm and 4pm today'
d. refers to a duration instance
m.duration(100); // 100 ms
m.duration(2, 'seconds'); // years, months, weeks, days, hours, minutes, seconds, milliseconds

d.add() // same as m.add()
d.subtract() // same as m.subtract()
d.humanize(); // a minute
