Date Difference Calculators
Choose a calculator to find the time between two dates.
Calculate the exact difference between any two dates in the unit of your choice — seconds, minutes, hours, days, business days, weeks, months, or years. Enter a start and end date (with optional times for extra precision) and get an instant result.
Use the Age Calculator to find your exact age in years, months, and days. The Business Days calculator excludes weekends automatically. Each calculator defaults to the most relevant unit, but you can switch to any unit at any time. All math runs locally in your browser — nothing is stored or sent to a server.
