Autumn: When Does It Start?
For most of us, autumn means falling leaves, shorter days, returning to school, and the more modern tradition of pumpkin spice lattes. But when does it officially begin? Well, that depends on which calendar you follow.
Meteorological Calendar
Many argue 1 September is when the seasons change, and they're right according to the meteorological calendar.
Celtic Calendar
In contrast, in the ancient Celtic calendar, we've already been in autumn since 1 August.
Astronomical Calendar
Yet, those adhering to the astronomical calendar claim we won't officially be in autumn until 23 September.
So, why do we have three calendars? And who will be using them in 2026?
Celtic Autumn - Lúghnasadh
Dozens gathered at a druid grove in County Kilkenny to celebrate Lúghnasadh – the start of autumn in the Celtic calendar. This ritual, led by Eimear Burke, Chosen Chief of the Order of Bards, Ovates and Druids (with 30,000 global members), marks the early harvest and "represents life, death, and rebirth."
Traditional Celtic Practices
Fiona Byrne, a history curator at the Ulster Folk Museum, explains that for ancient Celts, this was "vitally important to be prepared for the darker days of winter and to get the harvest in before All Hallows Eve (Halloween)."
In summary:
We have three calendars tracking autumn's start: meteorological, Celtic, and astronomical. Each holds cultural and historical significance, shaping how we perceive and celebrate this season.
