How it works

Duration accounts for varying month lengths and leap years. Common uses: age calculation, contract term verification, and billing period calculation. ISO 8601 duration format: P1Y2M3DT4H5M6S (1 year, 2 months, 3 days, 4 hours, 5 minutes, 6 seconds). Legal and financial contracts often use specific day-count conventions (actual/actual, 30/360)—confirm which applies.
