πŸ’‘ Precise Duration Between Any Two Dates

Enter a start and end date to see the exact difference broken down into years, months, and days β€” plus totals in days, weeks, and months. This is the same calculation used for age computation, tenure tracking, and project timeline analysis.

The calculator accounts for varying month lengths and leap years. It always gives the most human-readable breakdown: '2 years, 3 months, 15 days' rather than just '865 days' (though it shows both).

January 1 to October 15 = 9 months, 14 days = 287 total days = 41 weeks. Useful for tracking project timelines, relationship milestones, or event planning windows.
