pyarrow.compute.ceil_temporal#

pyarrow.compute.ceil_temporal(timestamps, /, multiple=1, unit='day', *, week_starts_monday=True, ceil_is_strictly_greater=False, calendar_based_origin=False, options=None, memory_pool=None)#

Round temporal values up to nearest multiple of specified time unit.

Null values emit null. An error is returned if the values have a defined timezone but it cannot be found in the timezone database.

Parameters:
timestampsArray-like or scalar-like

Argument to compute function.

multipleint, default 1

Number of units to round to.

unitstr, default β€œday”

The unit in which multiple is expressed. Accepted values are β€œyear”, β€œquarter”, β€œmonth”, β€œweek”, β€œday”, β€œhour”, β€œminute”, β€œsecond”, β€œmillisecond”, β€œmicrosecond”, β€œnanosecond”.

week_starts_mondaybool, default True

If True, weeks start on Monday; if False, on Sunday.

ceil_is_strictly_greaterbool, default False

If True, ceil returns a rounded value that is strictly greater than the input. For example: ceiling 1970-01-01T00:00:00 to 3 hours would yield 1970-01-01T03:00:00 if set to True and 1970-01-01T00:00:00 if set to False. This applies to the ceil_temporal function only.

calendar_based_originbool, default False

By default, the origin is 1970-01-01T00:00:00. By setting this to True, rounding origin will be beginning of one less precise calendar unit. E.g.: rounding to hours will use beginning of day as origin.

By default time is rounded to a multiple of units since 1970-01-01T00:00:00. By setting calendar_based_origin to true, time will be rounded to number of units since the last greater calendar unit. For example: rounding to multiple of days since the beginning of the month or to hours since the beginning of the day. Exceptions: week and quarter are not used as greater units, therefore days will be rounded to the beginning of the month not week. Greater unit of week is a year. Note that ceiling and rounding might change sorting order of an array near greater unit change. For example rounding YYYY-mm-dd 23:00:00 to 5 hours will ceil and round to YYYY-mm-dd+1 01:00:00 and floor to YYYY-mm-dd 20:00:00. On the other hand YYYY-mm-dd+1 00:00:00 will ceil, round and floor to YYYY-mm-dd+1 00:00:00. This can break the order of an already ordered array.

Alternative way of passing options.

memory_poolpyarrow.MemoryPool, optional

If not passed, will allocate memory from the default memory pool.
