Maximum and Minimum Date

The date range in the calendar can be set using the dateMin and dateMax parameters. These parameters specify the allowed range of dates in the calendar.

By default, the minimum date is '1970-01-01', which corresponds to the beginning of UNIX time. The maximum date is set to '2470-12-31' by default and is chosen arbitrarily.

If you need to set a specific range of possible dates, replace the values of the dateMin and dateMax parameters with the dates you need. Note that the calendar will not process dates outside the specified range.
