The Ogham calendar is a fascinating ancient system of timekeeping that was used in Ireland more than a thousand years ago. It is named after the Ogham script, a form of early medieval writing that was used primarily in Ireland and parts of Britain. While the Ogham script was used primarily for inscriptions on stones and wood, the Ogham calendar was used to mark the passage of time and to keep track of important events and festivals.
The Ogham calendar is believed to have originated in the 4th or 5th century and is thought to have been used until the 11th or 12th century. The calendar was based on a lunar year, with each month consisting of either 29 or 30 days. This meant that the calendar was adjusted every few years to keep it in line with the solar year, which has 365 days. The Ogham calendar was divided into two halves, with the first half consisting of the months of Bealtaine, Samhain, Imbolc, and Lughnasadh, and the second half included the same months, but in a different order
Each month in the Ogham calendar was associated with a particular tree or plant, and each of these plants was believed to have special properties and significance. For example, Bealtaine, which was celebrated in May, was associated with the hawthorn tree and was believed to bring good luck and prosperity. Samhain, which was celebrated in November, was associated with the yew tree and was believed to be a time of reflection and renewal.
One of the most interesting aspects of the Ogham calendar is its connection to the natural world. The Ogham calendar was based on the cycles of the moon and the seasons, and it was believed that the cycles of nature were closely tied to the cycles of the calendar. This meant that the Ogham calendar was not only a system of timekeeping, but it was also a way of understanding and connecting with the natural world.
Despite its ancient origins, the Ogham calendar is still remembered and celebrated in Ireland today. Many modern-day pagans and druids celebrate the Ogham calendar and the festivals associated with each month, and they continue to honor the traditions and beliefs of the ancient people who created the calendar.
