Julian Cope presents Head Heritage

Well completely off the cuff, Happy Imbolic everyone. But could someone tell me whether it is today. tomorrow or the 4th February. The four seasonal festivities of the year, are presumably on the 1st day of their months. But then if they have been messing around with the calendars over time it doesn't really matter.......
The Coligny calender 'celtic' though roman lettering and found in a roman temple does not have the dates?, so presumably the Irish annals must be the right source.
