About Date & Time Calculator

Date & Time Calculator was built by a team of developers and productivity enthusiasts who were tired of complicated, ad-heavy tools that made simple date math harder than it needed to be.

Our mission is simple: provide accurate, fast, and free date and time tools for students, professionals, HR teams, freelancers, and anyone who needs to work with time.

We support 24+ global timezones, US federal holidays, business day calculations, and more — all with a clean interface that works beautifully on any device.
