In-depth explanation
Enter a date of birth (and optionally a custom end date) to see total days lived, plus approximate weeks, hours, and minutes. Everything runs locally in your browser — your inputs are not uploaded to produce the result.
The day count uses calendar dates, so 29 February in leap years is counted when it falls in the range. Change the “Calculate on” date to any day on or after the date of birth.
Age Calculator shows years, months, and days. This tool focuses on the total day count and related units. Tweak the inputs above to compare options, then copy or note the result you need.
