Days in a Month
Find out how many days are in any month of any year.
Why February changes
Every month has a fixed length except February, which has 28 days in a normal year and 29 in a leap year. This tool accounts for that automatically based on the year you choose.
Useful for billing cycles and scheduling
Knowing exactly how many days a given month has matters for prorated billing, payroll cycles, and scheduling recurring events — and February is the one that trips people up, since it's 28 days most years but 29 in a leap year. Pick any month and year and get the exact day count instantly, leap years handled automatically.
