Why today matters
Today's Gregorian date is the global civil standard — the calendar of passports, contracts, news reports, train timetables, software systems, scientific publications, and international treaties. Even countries that maintain a parallel religious or national calendar (Iran with its Solar Hijri, Israel with the Hebrew, Saudi Arabia with the Islamic, Ethiopia with the Ge'ez, Japan with its imperial nengō) use the Gregorian calendar for international interaction. Today, Wednesday, November 4, 2026, is day 308 of 2026 — week 45 in ISO 8601 reckoning.
Pope Gregory XIII's 1582 reform was, on its surface, a 10-day correction — but it has turned out to be the world's most successful piece of timekeeping legislation. Four centuries on, no one can imagine running an airline schedule by any other calendar.
How we compute this
Gregorian is a solar calendar. Each year contains 365 days; 366 in leap years (every 4 years, except centuries not divisible by 400), with each month averaging 28–31 days. Years are counted from Anno Domini 1 — calculated by the monk Dionysius Exiguus in 525 CE (era: AD (Anno Domini) / CE (Common Era)).
The Gregorian calendar was promulgated by Pope Gregory XIII on 24 February 1582 in the papal bull Inter gravissimas, replacing the Julian calendar that had been in use since Julius Caesar's reform of 45 BCE. The reform did two things: it corrected a 10-day drift that had accumulated against the spring equinox (Thursday 4 October 1582 was followed by Friday 15 October 1582), and it adjusted the leap-year rule to drop three leap days every 400 years (years divisible by 100 but not 400 are no longer leap, so 1700, 1800, and 1900 were ordinary years; 2000 was a leap year). Adoption was slow and politically charged: Catholic countries (Spain, Portugal, Italy, the Papal States, France) switched immediately in 1582–1583. Protestant and Orthodox countries resisted on religious grounds for centuries. Britain and its American colonies switched in September 1752, skipping eleven days (the "Eleven Days Riot" of British folklore is largely apocryphal, but the change was real). Russia switched in 1918 under the Bolsheviks. Greece switched in 1923. Turkey in 1926. Saudi Arabia adopted the Gregorian calendar for civil business in 2016 — the last major holdout. Eastern Orthodox churches continue to use the Julian calendar for liturgical purposes, which is why Russian Orthodox Christmas falls on 7 January (= 25 December Julian).
Used by: Virtually every country on earth — the de facto global civil standard. Regions: Universal civil use; adopted progressively from 1582 to 2016.
