This is the final part of our Excel Date Tutorial that offers an overview of all Excel date functions, explains their basic uses and provides lots of formula examples. Microsecondes (ajouté en PHP 5.2.2). Notez que la fonction date() génèrera toujours 000000 vu qu'elle prend un paramètre de type entier, alors que la méthode DateTime::format() supporte les microsecondes si DateTime a été créée avec des microsecondes.

Like most of Excel date functions, EOMONTH can operate on dates input as cell references, entered by using the DATE function , or results of other formulas. Salads: Chopped, sliced, or pitted whole dates are an excellent addition to salads. It can be a cell reference, a date entered by using the DATE function , or returned by other formulas.

It could even prompt for date (and it you get really clever, only prompt for dates if there could be more options than today's date). Unless you specify a time zone offset, parsing a string will create a date in the current time zone. You can pass an integer into each of those functions to get a specific month or weekday.

When numbers are used to represent months, a significant amount of confusion can arise from the ambiguity of a date order; especially when the numbers representing the day, month or year are low, it can be impossible to tell which order is being used.

This is a pretty robust function for adding time to an existing moment. Note: moment#startOf('week') was added in version 2.0.0. The TODAY() function returns today's date, exactly as its name suggests. 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.

Locale#months should be an array of the month names. To get the current date and time, use the NOW function. The value returned by TODAY will continually update each time the worksheet is recalculated (for example, each time a cell value is entered or changed).

The months of April, June, September, and November have 30 days, while the rest have 31 days except for February, which has 28 days in a standard year, and 29 in a leap year. Finally, Moment will search intelligently through an array of locales and their substrings.

As of version 2.1.0, moment#startOf('week') uses the locale aware week start day. The date (Unix) command—internally using the C date and time functions —can be used to convert that internal representation of a point in time to most of the date representations shown here.

In order to stop mixed-type comparisons from falling back to the default comparison by object address, when a timedelta object is compared to an object of a different type, TypeError is raised unless the comparison is == or !=. The latter cases return False or True , respectively.

It is sometimes useful to get the list of months or weekdays in a locale, for example when populating a dropdown menu. A calendar date is a reference to a particular day represented within a calendar system. You can use the ( ) function to convert character data to dates.

For these, the lowercase tokens use the locale aware week start days, and the uppercase tokens use the ISO week date start days. Moment will also try locale specifier substrings from most-specific to least-specific until it finds a locale it knows. Note that in order to make the operations (-.5, 'days') and moment.subtract(.5, 'days') equivalent, -.5, -1.5, -2.5, etc are rounded down.

If datetime instance d is naive, this is the same as d.timetuple() except that tm_isdst is forced to 0 regardless of what () returns. A datetime object is a single object containing all the information from a date object and a time object. You are returned to the calendar to choose a date.
