There's something called the proleptic Gregorian calendar, produced by
extending the rules for the Gregorian calendar back to dates preceding
its introduction. It's used fairly widely.
https://en.wikipedia.org/wiki/Proleptic_Gregorian_calendar
Note also that in the US consider George Washington's birthday is
considered to be February 22 (NS, new style), even though that date was
February 11 (OS) under the Julian calender then in effect.
