About DateDelta

DateDelta is a small, free tool for two everyday date questions: exactly how old someone is, and exactly how far apart two dates are. It was built to do one job well: give you an instant, accurate answer without asking for an account, a payment, or your data.

Everything happens in your browser using standard calendar math — the dates you enter are never sent to a server or stored anywhere. Age results include a countdown to the next birthday; date-difference results include total days, weeks, and weekdays.

DateDelta is supported by ads shown alongside the tool, which keeps it free to use with no limits. It's one of a growing set of small tools at Laborilo.
