Leap Year
Yes. 2040 is a leap year.
February 2040 has 29 days, and the year has 366 days total.
2040 is divisible by 4 and not divisible by 100, so it's a leap year under the standard rule.
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 2040: 2044. Previous leap year before 2040: 2036.
