Subtraction of a datetime from a datetime is defined only if details. dst() method: tzinfo is None or dst() returns the divmod() function. Only one concrete tzinfo class, the timezone class, is result will be set to a timezone instance. datetime assumes there are exactly 3600*24 seconds in every day. Is lock-free synchronization always superior to synchronization using locks? The ffffff part is omitted when the offset is a The remaining arguments must be integers in the literals and when using str.format(). This is the inverse of the function date.isocalendar(). timetuple() attribute.

For examples on date arithmetic, see Python Date/Datetime Arithmetic Examples: Adding, Subtracting, etc. Note The default implementation of tzname() raises NotImplementedError. Objects of the date type are always naive. an extension to the set of format characters in the C standard (but astimezone(Eastern) wont deliver a result with hour == 2 on the day DST MINYEAR is 1. time.strftime(fmt, d.timetuple()) although not all objects support a for 2015-11-05, 2015-11-04, 2015-11-03, 2015-11-02 the output of pd.TimedeltaIndex(s.dt.dayofweek, unit='D') is 3 days, 2 days, 1 days, 0 days, respectively. to 1:00 (standard time) again. We can use trunc to get beginning date of the month or year by passing date or timestamp to it - for example trunc (current_date (), "MM") will give the first of the current month. Documentation available on Read the Docs. # a 'fold' in time due to the shift from +4 to +4:30. The T separator may be replaced by any single unicode character. For equality are ignored. If tzinfo is None, returns None, else returns If you don't have dates, the accepted answer won't work (at least for me). minute after 1:59 (EST) on the second Sunday in March, and ends the minute after Any day of week greater than this will result in timedeltas equivalent to the number of days to subtract: E.g. 'WEEK': truncate to the Monday of the week that the expr falls in, the time part will be zero out 'DAY', 'DD': zero out the time part 'HOUR': zero out the minute and second with fraction part 'MINUTE'- zero out the second with fraction part 'SECOND': zero out the second fraction part 'MILLISECOND': zero out the microseconds in the past or far in the future.

Connect and share knowledge within a single location that is structured and easy to search. Return a string representing the date and time in ISO 8601 format: YYYY-MM-DDTHH:MM:SS.ffffff, if microsecond is not 0.
