About

OfficeOpenToday is a reference site for public holidays, bank holidays and calendars. It answers one kind of question: what date is a holiday, what day of the week does it fall on, and is it observed on a different day. Everything else on the site exists to get you to that answer faster.

It currently publishes the 11 United States federal holidays in depth, plus 12 US civic dates, Canada public holidays, and United Kingdom bank holidays for England and Wales (Canada, United Kingdom, United States), with month and year calendars covering an eight-year window.

Two groups, served on the same pages. Most visitors arrive from a search engine with a specific question and no patience — they get the answer on the first screen, above anything else. A smaller group is planning: office schedules, leave, payroll runs, term dates. They get the calendars, planners and multi-year tables further down the page.

Neither audience displaces the other. The answer sits on top; the planning material sits underneath.

Dates are calculated from the rule that defines the holiday, not copied from another calendar. "The fourth Thursday in November" is applied in code, so every year in the published window is internally consistent and no year has to be typed in by hand. That removes the most common failure on calendar sites, which is a single mistyped year that nobody notices.

Every holiday carries its legal basis and the sources it was checked against, each with the date it was last verified, printed on the page. The build fails on any entry that is unsourced or more than twelve months stale, so a stale page cannot quietly ship.

The site needs no JavaScript to be read or used. Every date is in the HTML.

It does not tell you whether a particular shop, bank branch or office is open. That depends on the individual business, changes without notice, and cannot be stated accurately at national scale — so it is not claimed.

It does not publish unsourced observances. Novelty days circulate widely without any authority behind them; a date here has a source or it is not published.
