Why does my age in months or days look different from other calculators?
Some calculators round differently. This tool calculates the exact elapsed time accounting for leap years and actual month lengths, so results reflect your true age rather than a rounded estimate. Conventions differ particularly for dates near the end of months (e.g. born January 31).
