A Celtic lunisolar calendar has been reconstructed from fragments of two second AD calendars found in the French town of Coligny. The first month on this calendar is called ''Samonios''. The Celts celebrated a three-day festival that began on the 17th of ''Samonios'', according to the calendar.<ref name="Olmsted">Olmsted, Garrett (2009). ''The Coligny Calendar: the Implications for Gaulish and Irish Festival Dates''.</ref> This festival may correspond to Beltaine, the most important Celtic holiday. Either 17 Samonios was understood to correspond to May 1, or change of season dates were placed on the first of the month for convenience. Samhain followed Beltaine by six months. The calendar may have originally started on the day of summer solstice (June 21) and migrated due to calendar drift.
