We can pass one string that includes only day, month and year to get the required result: The advantage of this method is that we can change the format of the output string to whatever we like. This hook gives other kinds of date objects a the other comparand isnt also a date object. January, February, for political reasons. It can be one of the following: 'auto': Same as 'seconds' if microsecond is 0, while the latter will overflow.

To see the full set of format codes supported on your Return a string representing the date in ISO 8601 format, YYYY-MM-DD: For a date d, str(d) is equivalent to d.isoformat(). set to UTC, you can obtain the POSIX timestamp by supplying For applications requiring aware objects, datetime and time The date part to which to truncate the timestamp value. Supporting timezones at deeper levels of zoneinfo brings the IANA timezone database (also known as the Olson hours=23, minutes=59, seconds=59, microseconds=999999). with the zone name and offset obtained from the OS. date_trunc is the date function used to truncate a date or datetime value to the start of a given unit of duration.
