september, minus a few days
This is quite interesting:

…for the uninitiated, that is the September calendar from 1752. Notice that there are a few missing days :-)
No, the GNU “cal” program doesn’t have a bug in it. September 1752 was when Great Britain replaced the Julian calendar with the Gregorian calendar. When that transition occurred, there was an eleven-day offset between the two calendars, so “officially”, the date skipped from September 2nd to the 14th.
I thought that was interesting…
