June 21 marks the Summer Solstice in 2018 when the ancient Celts would have celebrated the longest day of the year with a local bonfire, song, and dance but what other feast days were of importance to our ancient ancestors?

Sol 1

Tomorrow we celebrate the summer solstice but there are eight sacred days in Ireland in total, the times when the old Celtic world stopped to celebrate. Christianity adapted many of their feast days to match.

St. Brigid’s Day

sol 2

The years’ first sacred holiday, the feast day of Saint Brigid, is celebrated on February 1, marking the beginning of Spring. The Bogha Bríde or Brigid’s Day Cross is the symbol of the day. Traditionally, reeds or straw are collected from the fields and crafted into a cross. St. Brigid is Ireland’s most celebrated female saint and was the Abbess of one of the first convents in Ireland.

St. Patrick’s Day – Spring Equinox

Around the globe, Irish people and those of Irish descent celebrate St. Patrick’s Day on March 17, which is one of Ireland’s biggest holidays. The special holiday is devoted to the patron saint of Ireland. The religious day is marked by a special mass for the feast and traditionally everyone wears green. This is considered the middle of the Spring season and is also referred to as the Vernal Equinox.

May Day – Bealtaine

May Day, the 1st of May in Ireland, is a Holy Day which marks the start of the summer season. Centuries ago, bonfires were lit to welcome the arrival of summer. In Ireland, depending on what day the holiday falls, the feast is marked by a public holiday. In towns around the country, May Fair days are held where farmers and traders all gather in towns to sell their wares.

Midsummer – Summer solstice

The summer solstice is marked in parts of Ireland by bonfires on the side of the road. It is usually celebrated on June 23 (this year it will be on June 21), the longest day of the year. In rural Ireland, communities gather and for their local bonfire and celebrate the longest day of the year with song and dance.


sol 6

In ancient times, this sacred day marked the beginning of harvest on August 1. It honored the Celtic God of Lugh. In Gaelic folklore, it was a time for handfastings or trial marriages that would last a year and a day could be renewed. Many celebrate the holiday today with re-unions, bonfires and dancing.

Autumnal Equinox

sol 7

This day falls between two days: Oíche Shamhna (October 31) and Lá na Marbh (November 2). Oíche Shamhna is Halloween and Lá na Marbh, is the Day of the Dead, or All Souls Day, when those who have passed away are remembered. It marks the beginning of the “darker half” of the year as the winter approaches.

Winter Solstice

Newgrange, Co. Meath

The winter solstice celebrates the shortest day of the year and, depending on the year, occurs between December 21-23. Annually hundreds of people gather in Newsgrange, Co. Meath to watch the sunrise and magically illuminate the ancient burial site.
