The Nerdy Sixty | (51/60) Missing September Days | Solution

Run `cal 9 1752`. You’ll see 11 days missing. Why are those dates skipped?

Hint 1: This was due to a historical calendar reform in 1752.

Hint 2: Britain (and colonies) switched from Julian to Gregorian, dropping 11 days in Sept 1752.

Solution:

`cal 9 1752` shows that September 3–13, 1752 are missing. This is because the British Empire transitioned to the Gregorian calendar, “losing” 11 days (September 2 was followed by September 14, 1752) to correct the calendar alignment.
