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.

timestampsArray-like or scalar-like

Argument to compute function.

multipleint, default 1

Number of units to round to.

unitstr, default “day”

The unit in which multiple is expressed. Accepted values are “year”, “quarter”, “month”, “week”, “day”, “hour”, “minute”, “second”, “millisecond”, “microsecond”, “nanosecond”.

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.

optionspyarrow.compute.RoundTemporalOptions, optional

Alternative way of passing options.

memory_poolpyarrow.MemoryPool, optional

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