So this request is a bit of a niche one but with the new date picker, any year that is anterior to 1800 automatically switches to 1800 when you try to type it.
To replicate:
  • Create an object with a Date property
  • Set a date in the date picker (eg: 01-01-1799)
  • Year turns to 1800
The calendar is a very useful and visual way to make historical timelines so it would be great to have this work!
