 About 1400 it is recorded that St Bega's day was celebrated 'in albs' (for a lesser saint) at the mother house of St Mary's Abbey, York.A fifteenth-century Book of Hours in the Bodleian Library from St Mary's records the day as 7 November.Since this discovery in the late 20th century, St Bega's day has been celebrated in St Bees on this date.
