Sunday 29 December is St Thomas of Canterbury Day when the murder of Archbishop Thomas Becket during Christmas 1170 is remembered.
It will be a low-key day as this year it is a Sunday when most churches are keeping Holy Family Sunday or First Sunday of Christmas.
At Canterbury Cathedral there is evensong at 3.15pm when the service includes a procession to the Martyrdom for a liturgical reading of lines from TS Eliot’s Murder in the Cathedral. The service ends in the crypt.
Thomas Becket was murdered during Vespers in the late afternoon and Solemn Vespers will be sung in the crypt at 8pm.
Next year, a leap year, the 850th anniversary will fall on a Tuesday and be widely marked especially at Canterbury.
