About Us

YearsAgoCalculator is a free collection of date and time calculators. We started with one simple question that people search for every day, "what was the date X years ago?", and built a fast, accurate tool to answer it.

Today the site offers 25 calculators in 20 languages, covering years, months, weeks and days ago or from now, date differences, exact age, birth year, leap years and the day of the week for any date. Every calculation runs in your browser using real calendar rules.

Our blog publishes plain-language answers and guides about calendar math. If you spot an error or want a new calculator, please contact us.
