Our age calculator computes your exact age from your birth date to today (or another end date), in years, months, and days. It is handy for forms, eligibility checks, or simply satisfying curiosity. The date calculator finds the number of days between two dates, or the date that is a given number of days before or after a start date. This helps with project timelines, deadlines, and countdowns.
Tracking elapsed time is common for work, study, or events. Our hours calculator lets you add or subtract time intervals (hours and minutes) so you can total work hours, duration of activities, or time between start and end. All date and time tools use the Gregorian calendar and do not account for local daylight saving or time zone rules unless you enter times that already reflect them.
Use these calculators for planning and estimation. For legal or official purposes (e.g., age verification, payroll), always follow the rules and systems required by your organization or jurisdiction.
