Leap Year
No. 2066 is not a leap year.
February 2066 has 28 days, and the year has 365 days total.
2066 is not divisible by 4, so it is a common year with 28 days in February.
The rule in full: a year is a leap year if it's divisible by 4 — except century years (divisible by 100), which are only leap years if they're also divisible by 400. That's why 2000 was a leap year but 1900 and 2100 are not, despite all three being divisible by 100.
Next leap year after 2066: 2068. Previous leap year before 2066: 2064.
