A focused date and time reference.
The site is built to answer simple elapsed-time questions quickly, then provide useful calendar context without burying the answer.
What is covered
Exact date pages, date arithmetic, recurring calendar dates, clock times and named annual observances. The recurring event section uses a reviewed observance dataset rather than inventing event dates from search snippets or secondary lists.
What is deliberately not multiplied
Related units are answered together on one useful page. A single event page can show days, weeks, hours, minutes and seconds without making the user jump between nearly identical pages.
