10 Ancient Celtic Holidays to Celebrate in Ireland

The ancient Irish lived a simple agricultural life and based their time around the seasons – spring, summer, fall and winter. For the ancient Celts to mark the passing of the seasons they created Celtic holidays to celebrate the various significant dates on their calendar.  

Known as the ‘cross-quarter’ festivals the biggest Celtic holidays were Imbolc, Bealtaine, Lughnasadh and Samhain. The sacred celebrations were timed to match seasonal events and were coordinated with the movement of the sun across Irish skies.

The Sacred Fire Festivals of Ireland are Imbolc, Beltane, or Bealtaine, Lughnasadh and Samhain. The Celtic year was divided into two halves, the dark and the light. Samhain was the beginning of the dark half, with its counterpart, Beltane beginning the light half. Between these two ‘doors’ or portals fell Imbolc, on February 1, and Lughnasadh or Lammas, celebrated on August 1, quartering the Celtic year. These quarters were again divided by the solstices and equinoxes, which were known as the four Albans.

Michaelmas – September 29th


Michaelmas, or the Feast of Michael and All Angels, is celebrated on the 29th of September every year, this is a Christian holiday celebrated by both Catholics and Protestants. As it falls near the equinox, the day is associated with the beginning of autumn and the shortening of days.

During the Middle Ages, Michaelmas was a great religious feast and many popular traditions grew up around the day, which coincided with the harvest in much of western Europe. It was the custom to eat goose on Michaelmas, which was supposed to protect against the financial need for the next year. This is also the last day for picking blackberries which are the filling in Michaelmas pies. The name Michaelmas comes from a shortening of “Michael’s Mass”.

Where is Michaelmas Celebrated in Ireland? In ancient Ireland, it was the Anglo-Normans and the establishment of their customs that gave Michelmas its place on the Irish calendar. In several towns, Michaelmas was the day to elect a mayor, tradition says that the Mayor of Dublin could not be sworn in until after his counterpart in Drogheda. Where this custom came from, no one seems to know. In Waterford, they would hold a procession to the beach and cast an effigy of St. Michael into the sea as a symbolic protest against the loss of earnings.

The autumnal equinox – approx Sept. 21st

Mabon or Alban Elved (Light of the Water) celebrates the day and night before the darkness overtakes the light in other words winter is coming. It is also the last harvest before winter sets in where pagans celebrate and thank earth in her role as Mother and Giver for the good harvest. Alban Elved is the Druidic name for the Autumn Equinox where the night and day are equal and it is a rare magical day due to that balance of light and dark.

Mabon is one of the eight Wiccan sabbats celebrated during the year. In mythology, Mabon is the time when the God of Light was defeated by the God of Darkness, resulting in longer nights. In Celtic folklore, Mabon is the son of Modron, the Great Goddess of the Earth, who was kidnapped for three days after his birth making the light go into hiding.

Samhain is the ancestor of Halloween and is seen as the time when the veil between worlds thins and the spirit can pass through to communicate with the living.

In Gaelic “samhraidhreadh” means “summer’s end”, or the beginning of the dark days (winter). Irish “Samhain” means the month of November and is celebrated as Celtic New Year’s Eve and the final harvest before winter sets in. Much like the Mexican Day of the Dead gifts of food, drink and toys for the children who passed are laid out.  Fires are lit from the sacred bonfire and the seanchaí tells ancient tales beside the fires.

Irish folklore as told by the bards and storytellers says that in the three days preceding Samhain, the Sun God Lugh, maimed at Lughnassadh, dies by the hand of his Tánaiste (heir), the Lord of Misrule. Lugh crosses the veil of the world on the first day of Samhain. His heir is miserly and that is why the sun in winter gives no heat and doesn’t protect the land from the north winds and cold.

It is the time of re-birth when the last of the harvest foods is used to celebrate the coming of spring. The Druids called this Alban Arthuran (Light of Arthur, Fire Festival) or Yule meaning Christmas.

Traditions around Yule include gathering mistletoe from oak trees, in an attempt to ward off evil spirits and grant good luck. According to an old Celtic myth, on the solstice the Oak King, representing the light, and the Holly King, representing the dark, would fight, with the Oak King emerging victorious at the winter solstice, enabling the return of the light.

Imbolc – St. Brigid’s Day – Feb 2nd

Imbolc is a Wiccan and Celtic pagan holiday, that is sometimes referred to as Candlemas or Oimelc. Imbolc symbolizes the halfway point between the winter solstice (Yule) and the spring equinox (Ostara) and is the second Celtic Fire Festival.
Ceremonies involve water, candles pledges and planting a hope or a seed, making candles

Interestingly Imbolc evolved into Groundhog Day in North America as both falls on the same day. To celebrate Imbolc, some modern-day pagans focus on celebrating Brigid. They do this by setting up an altar with the symbols of Brigid, like a corn husk doll, white flowers, a bowl of milk, and candles. If there is a group gathering, they might cast a circle, and recite a prayer to receive a blessing from Brigid

 Irish Pagan tradition says that Cailleach a Gaelic goddess gathers firewood on Imbolc for the rest of the winter. If the day is sunny, she gathers a great deal of wood, thusly the winter will continue for some time. If the day is rainy, she will not gather much wood and the remaining winter will be short. Over time this celebration became Christianized and called St. Brigid’s Day.

St Brigid’s Day was the festival of fertility and marked the beginning of spring in Ireland. It signalled an end to the darkness of winter and ushered in a new season of hope and growth.
