This thread is resolved. Here is a description of the problem and solution.
Problem: I would like to use a datepicker to select a date before 1583.
Solution: It's not possible to use Toolset's datepickers to save dates outside of the date range 15/10/1582 to 31/12/3000, according to our developers.
I think one alternative approach here would be to use a Number field instead of a datepicker field. If you only need the Year, that's pretty straightforward. However if you need to save a full date (year, month, day), it will require more information. Toolset datepickers save epoch timestamps in the database, so you could use the same approach.
Date: 28/01/1582 0:00:00 GMT
Epoch timestamp: -12241756800
So to save the date Jan 01 1582, you would save -12241756800 in the custom field.
Then you could use a custom shortcode to format that custom field timestamp as a date using PHP.
