About Datewise

Simple, fast date and time tools that give a clear answer.

Datewise counts days between dates, adds business days, works out ages, counts down to events and compares time zones. It covers public holidays for Australia, the United Kingdom, the United States, Canada, New Zealand, Ireland and India, so working-day counts leave out the right days for where you are.

Holiday dates are checked against official government sources. Every page links to the source it was checked against; if you spot something that has changed, please let us know.

All the calculations run in your browser. The site is free and supported by advertising, and Datewise Pro removes the ads.
