Marymass is the Scottish name for the feast of the Assumption on 15th August. A Celtic festival by the name of Marymass was been celebrated in mid-August as early as the 7th century, with some festivals having actual records that go back to about the year 900.
Very early on, the Church chose August 15th to honor the Assumption of the Blessed Virgin Mary. August 15 would be the full moon of August if the new moon fell on the first of the month as it did during the time of the lunar calendar. It was proclaimed a holiday throughout the Roman Empire by Emperor Maurice around 600 in the East, and about 50 years later in the West. Common Celtic people would not have been aware of the theological doctrine of the assumption—that Mary did not die but was taken bodily up into heaven at the end of her earthly life. However, Celts would have associated Mary with the fruitfulness of the earth at the time of harvest, and celebrations connected to other harvest goddesses were transferred to Mary as the pagan Celtic lands were converted to Christianity. Representations of Mary often resembled the ancient depictions of harvest goddesses wearing robes decorated with ears of corn.[ ]

A version for the Southern Hemisphere.
Oimelc ( Imbolc ) is the corresponding season to Lammas in the Southern Hemisphere
Northern Hemisphere Date: February 2nd
Also known as Imbolg, Candlemas, Feast of Torches, Oimelc, Lupercalia and Brigid’s Day.
Imbolc is the time of the beginning of beginnings, the time to consider carefully what you will do with the year stretching before you. Imbolc brings the awakening of the life force when the first green shoots of bulbs appear. Life is stirring again and this marks the Goddess recovering after giving birth while the newborn God is depicted as a small child nursing from his mother. The God is growing, spreading sunshine all around causing things to grow. It is a time to honour the feminine and get ready for spring. At lmbolc, the Australian forests are bright with the colour yellow, the Acacia trees coming into full flower. Until fairly recently, the 1st of August was “Wattle day” in Australia (it has now been moved to the 1st of September).[ ]
Saint Brigid of Kildare or Brigid of Ireland (Irish: Naomh Bríd; Latin: Brigida; c. 451 – 525) is one of Ireland’s patron saints, along with Patrick and Columba. Irish hagiography makes her an early Irish Christian nun, abbess, and foundress of several monasteries of nuns, including that of Kildare in Ireland, which was famous and was revered. Her feast day is 1 February, which was originally a pagan festival called Imbolc, marking the beginning of spring. Her feast day is shared by Dar Lugdach, whom tradition says was her student and the woman who succeeded her.
The saint shares her name with an important Celtic goddess and there are many legends and folk customs associated with her. Some scholars suggest that the saint is merely a Christianization of the goddess. Others suggest that she was a real person who took on the goddess’s attributes
