Good to know
Rule: a year is a leap year if it is divisible by 4, except century years, which must also be divisible by 400. So 2024 and 2000 are leap years, but 1900 and 2100 are not.
A leap year has 366 days, with 29 days in February. The extra day keeps the calendar in step with the Earth's orbit, which takes about 365.2425 days.
India uses the Gregorian calendar for official dates. Years before 1583 are worked out on the same rule (the proleptic Gregorian calendar), which may differ from historical records.
