Leap Year
No. 1977 is not a leap year.
February 1977 has 28 days, and the year has 365 days total.
1977 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 1977: 1980. Previous leap year before 1977: 1976.
