Frequently asked questions
How do I calculate the number of days between two dates?
Pick a start date and time and an end date and time, and the result shows the exact duration broken down into years, months, days, hours, minutes, and seconds, plus the total in each unit.
Can I calculate duration down to the hour and minute, not just days?
Yes, you set both a date and a time for the start and end points, so the result includes a precise breakdown down to the minute and second, not just whole days.
Is this duration calculator accurate across leap years?
Yes, the calculation accounts for actual calendar lengths, including leap years and varying month lengths, so the years, months, and days breakdown reflects real calendar time rather than a rough estimate.
Can I use this to calculate someone's exact age?
Yes, set the start date to a birth date and the end date to today, and the tool shows the exact age in years, months, and days, along with the total number of days lived.
