MaxDate

MaxDate[{date1, date2, ...}] gives the latest date of the dates.

• MaxDate[interval] gives the endpoint of the date interval.
• MaxDate[interval, gran] gives the endpoint of interval as specified by granularity gran.

Examples

Find the latest date:

MaxDate[{DateObject[{2020, 1, 1}], DateObject[{2023, 6, 15}], DateObject[{2021, 12, 31}]}]

Get the end of a date interval:

MaxDate[DateInterval[{DateObject[{2020, 1, 1}], DateObject[{2023, 12, 31}]}]]

With granularity:

MaxDate[DateInterval[{DateObject[{2020, 1}], DateObject[{2023, 6}]}], "Month"]
