class date – Represent a date

A representation of a date, according to the Gregorian calendar.

date objects support equality and comparison operators.

class datetime.date(year, month, day)

Construct a date object representing the given year, month and day.

Arguments must be integers in the following ranges:

• MINYEAR <= year <= MAXYEAR

• 1 <= month <= 12

• 1 <= day <= number of days in the given month and year

classmethod today()

Construct a date object representing today’s year, month and day.

classmethod fromtimestamp(timestamp)

Construct a date object representing the year, month and day specified by the provided timestamp.

A timestamp in this case is a floating point number representing the number of seconds since the epoch (January 1, 1970, 00:00:00 UTC).

classmethod fromordinal(ordinal)

Construct a date object representing the year, month and day specified by the provided ordinal.

An ordinal is an integer representing the number of days since January 1st of year 1.

classmethod fromisoformat(date_string)

Construct a date object from a string in ISO 8601 format:

from datetime import date
d = date.fromisoformat('2012-12-21')

min

The earliest representable date, date(datetime.MINYEAR, 1, 1).

max

The latest representable date, date(datetime.MAXYEAR, 12, 31).

resolution

The smallest possible difference between non-equal date objects, timedelta(days=1).

year

The year of the date, an integer in the range MINYEAR to MAXYEAR.

month

The month of the date, an integer in the range 1 to 12.

day

The day of the date, an integer in the range 1 to the number of days in the month represented by month.

replace(year=self.year, month=self.month, day=self.day)

Return a new date object with the same values as the existing date object, but with the specified parameters updated.

tuple()

Return the date as a 3-tuple (year, month, day).

timetuple()

Return the date as a 9-tuple (year, month, day, hour, minute, second, weekday, yearday, dst), as described in datetime.datetime.timetuple().

In this case:

• hour, minute and second are all 0, as the date object does not contain time information.

• weekday is the day of the week as an integer, where Monday is 0 and Sunday is 6.

• yearday is the day of the year as an integer, where January 1st is 1.

• dst is -1, as the date object does not contain daylight savings information.

toordinal()

Return an integer representing the ordinal of the date, where January 1st of year 1 has ordinal 1.

isoformat()

Return a string representing the date in ISO 8601 format, YYYY-MM-DD:

from datetime import date
date(2002, 12, 4).isoformat()
# outputs '2002-12-04'

isoweekday()

Return the day of the week as an integer, where Monday is 1 and Sunday is 7.

weekday()

Return the day of the week as an integer, where Monday is 0 and Sunday is 6.
