Oxfordshire Day is celebrated on 19 October to promote the historic English county of Oxfordshire.

[1] It is also the principal feast day of the patron saint of the city and university of Oxford, St Frideswide.

[2] The commemoration of St Frideswide's Day was encouraged in the nineteenth century by Henry Liddell, Dean of Christ Church.

[3] The feast day now appears in the calendars of the Diocese of Oxford[4] and the Roman Catholic Ordinariate of Our Lady of Walsingham.

[5] Each year there is a civic service to celebrate St Frideswide's Day in Christ Church Cathedral, Oxford, which houses her shrine.
