Basic Examples  (2)

By default, DateObject generates dates with calendar granularity determined by the input:

Use DateGranularity"Instant" to generate a date with "Instant" granularity:

By default, RandomDate dates are generated with "Instant" granularity:

Use DateGranularity"Day" to generate a pseudorandom day:

Generate dates with calendar granularity "Month":

Scope  (2)

Available granularity specifications depend on the calendar associated with the date:

DateGranularity specifies the output granularity, regardless of the input granularity for the given dates:
