Date Tools Hub is a small, focused collection of date calculators built to do one job well: answer everyday date questions instantly, on any device, without sign-ups, pop-ups getting in the way, or your data leaving your browser.
Every calculation runs locally in your browser using careful calendar arithmetic, so results are never distorted by time zones or daylight-saving changes. Public holiday dates are calculated from the standard published rules for the United States federal holidays and for England & Wales bank holidays. Governments can announce one-off changes, so for formal or legal deadlines please confirm with an official source.
The site is free to use. If you spot a mistake or would like another date tool added, please get in touch.
The tools stay free through a small amount of advertising and a few affiliate links to related products — for example, the paper calendars and planners linked from the homepage. As an Amazon Associate, this site earns from qualifying purchases — at no extra cost to you.
