The Gregorian Calendar is Adopted in Ireland and Britain

On September 2, 1752, the British Empire — including Ireland and its American colonies — adopts the Gregorian calendar, aligning its dating system with most of Western Europe, which had made the change over a century earlier.

The Julian calendar, introduced by Julius Caesar in 45 BCE, has a leap year rule that adds a day every four years. This makes the average year 365.25 days long, about 11 minutes and 14 seconds longer than the true solar year. Over centuries, this small error accumulates, causing the calendar to drift out of sync with the seasons. By 1752, the Julian calendar is 11 days ahead of the equinoxes, affecting the date of Easter and other seasonal events.

The Calendar (New Style) Act 1750 mandates the switch. To correct the drift, the Act declares that Wednesday, September 2, 1752, is immediately followed by Thursday, September 14, 1752 — effectively skipping September 3–13. This also adjusts the leap year rules to match the Gregorian system, omitting leap years in century years not divisible by 400.

The change is controversial. Britain and Ireland have been on the Julian calendar since 1582, with the New Year starting on March 25 (Lady Day). Adopting the Gregorian system means shortening 1751 to 282 days (March 25 to December 31) and aligning with Continental Europe, which had already made the switch in the 16th century.

Political debates, especially between the Whigs and Tories, reflect fears of losing sovereignty and of embracing “Popery.” While there are rumors of “calendar riots” demanding the return of the “lost” 11 days, these are likely exaggerated.

There are several impacts with making the change. There is historical confusion as dual dating (e.g., “Feb 10, 1750/51”) is common for decades. There are economic and social effects as birthdays, rent payments, and holidays are thrown off. The change also allows for international alignment as the change facilitates trade and communication with Europe.

The 1752 switch marks a turning point in British and Irish history, bringing the calendar into line with most of Europe and setting the stage for the Gregorian calendar’s eventual global dominance. Today, the Gregorian calendar is the world’s standard civil calendar, a legacy of this 18th-century reform.

Nollaig na mBan (Women’s Little Christmas)

Little Christmas, traditionally known as Nollaig na mBan or Women’s Little Christmas, takes place on January 6 each year. It is also known more widely as the Feast of the Epiphany, celebrated after the conclusion of the twelve days of Christmastide. It is the traditional end of the Christmas season and until 2013 was the last day of the Christmas holidays for both primary and secondary schools in Ireland.

Owing to differences in liturgical calendars, as early as the fourth century, the churches of the Eastern Roman Empire were celebrating Christmas on January 6, while those of the Western Roman Empire were celebrating it on December 25.

In October 1582, Pope Gregory XIII introduces the Gregorian calendar as a correction the Julian calendar, because the latter has too many leap years that cause it to drift out of alignment with the solar year. This has liturgical significance since calculation of the date of Easter assumes that spring equinox in the Northern Hemisphere occurs on March 21. To correct the accumulated error, he ordains the date be advanced by ten days. Most Roman Catholic countries adopt the new calendar immediately and Protestant countries follow suit over the following 200 years. For this reason, in some parts of the world, the Feast of the Epiphany, which is traditionally observed on January 6, is sometimes referred to as Old Christmas or Old Christmas Day.

In Ireland, Little Christmas is also called Women’s Christmas (Irish: Nollaig na mBan), and sometimes Women’s Little Christmas. The tradition, still strong in counties Cork and Kerry, is so called because Irish men take on household duties for the day. Goose is the traditional meat served on Women’s Christmas. Some women hold parties or go out to celebrate the day with their friends, sisters, mothers and aunts. As a result, parties of women and girls are common in bars and restaurants on this night.

In Ireland and Puerto Rico, it is the traditional day to remove the Christmas tree and decorations. The tradition is not well documented, but one article from a January 1998 issue of The Irish Times, entitled “On the woman’s day of Christmas,” describes both some sources of information and the spirit of this occasion.

A “Little Christmas” is also a figure in Irish set dancing. It refers to a figure where half the set, four dancers, join together with hands linked behind partners lower back, and the whole figure proceeds to rotate in a clockwise motion, usually for eight bars.

So, to all of the women of Ireland and the Irish diaspora, Nollaig na mBan shona daoibh!
