Date calculators for tracking time precisely.
Days ago, weeks ago, months ago and exact age — four small tools that answer a surprisingly common question.
"What date was that, exactly?" comes up more than you'd expect — tracking symptoms, planning a training block, checking how long ago a milestone was, or working out someone's precise age for a form. These four calculators handle that arithmetic instantly, counting forward or backward from today's date, or breaking down age into exact years, months and days.
Frequently asked questions
How do I find out what date it was X days ago?
Use the Days Ago calculator above: enter the number of days and choose "Before today," and it returns the exact calendar date, accounting for month lengths and leap years automatically.
How is exact age calculated?
The Age Calculator compares your birth date to today's date and breaks the difference down into full years, full months and remaining days — not just a rounded number of years — along with your total days lived and days until your next birthday.
