Instantly determine if a year is a common year or a leap year. Simple online tool for checking calendar days and year lengths.
Common Year Characteristics:
- Duration: Exactly 52 weeks and 1 day.
- February: Contains 28 days.
- Frequency: Three out of every four years are usually common years.
Why verify common years? This is particularly useful for financial calculations (interest accrual based on a 365-day year), project scheduling, and astronomical observations where the extra day in a leap year would skew results.
