How this page works it out

This page counts the midnights between two dates and shows the D-number. 2026-01-01 to 2026-12-25 is 358 days, D-358. That date is a Friday. 2026-01-01 to 2026-01-11 is 10 days, the same count as the date page.

The same day is 0 and D-Day. A past date uses D+ and the absolute number of days. An empty start counts from this device's date. An empty target stays a dash and does not become 0.

Adding both endpoints would turn the sample into 359, so this page leaves them out. It does not publish a holiday list. The count stays in this browser.
