DaySpan is a free reference site tracking 209+ events worldwide, providing live countdowns to upcoming occasions and exact day counts since historic moments.
Every future event page features a live countdown updating every second in your browser — showing days, hours, minutes and seconds remaining until the event. We cover global holidays, religious observances, sporting events, political elections, national days, seasons and awareness days across 135 upcoming events.
Every past event page shows the exact number of days elapsed since a historic moment, updating automatically at midnight each day. We cover 74 events spanning world history, modern events, science, sport, UK history and culture.
Fixed annual dates such as Christmas and national days are exact. Variable dates such as Easter and Jewish holidays are computed using established astronomical and calendar algorithms — the same methods used by professional calendar systems worldwide. Islamic dates (Eid, Ramadan) are projected estimates accurate to within ±1 day, subject to official moon sighting confirmation. All confirmed sports and political dates are sourced from official published announcements. Dates are refreshed annually.
DaySpan was built to give a clear, fast and accurate answer to two of the most commonly searched time-related questions on the internet: how many days until something happens, and how many days ago something happened.
