This is a list of adoption dates of the Gregorian calendar by country. For explanation, see the article about the Gregorian calendar.
Except where stated otherwise, the transition was a move by the civil authorities from the Julian to the Gregorian calendar. In religious sources it could be that the Julian calendar was used for a longer period of time, in particular by Protestant and Eastern Orthodox churches. The historic area does not necessarily match the present-day area or country. The column "Present country" only provides a logic search entry. With a few exceptions, the former colonies of European powers are not shown separately.
There are only four countries which have not adopted the Gregorian calendar for civil use: Ethiopia (Ethiopian calendar), Nepal (Vikram Samvat and Nepal Sambat), Iran (Solar Hijri calendar) [1] and Afghanistan (Lunar Hijri Calendar) [2] . Thailand has adopted the Gregorian calendar for days and months, but uses its own era for years: the Buddhist era. Many countries also continue to use traditional calendars for religious and ceremonial purposes.

The Julian day is the continuous count of days since the beginning of the Julian period, and is used primarily by astronomers, and in software for easily calculating elapsed days between two events.
An ecclesiastical new moon is the first day of a lunar month in an ecclesiastical lunar calendar. Such months have a whole number of days, 29 or 30, whereas true synodic months can vary from about 29.27 to 29.83 days in length. Medieval authors equated the ecclesiastical new moon with a new crescent moon, but it is not a phase of the true moon. If the ecclesiastical lunar calendar is accurate, the ecclesiastical new moon can be any day from the day of the astronomical new moon or dark moon to two days later. The ecclesiastical calendar valid for the Julian and Gregorian calendar are described in detail by Grotefend, Ginzel and in the Explanatory Supplement to The Astronomical Ephemeris.
