Following
The following of Saint Hilary developed in association with that of St. Martin of Tours as a result of Sulpicius Severus' Vita Sancti Martini and spread early to western Britain. The villages of St Hilary in Cornwall and Glamorgan and that of Llanilar in Ceredigion bear his name.
In France the majority of dedications to Saint Hilary are to be found to the west (and north) of the Massif Central from which areas the cult eventually extended to Canada.
In northwest Italy the church of Sant’Ilario at Casale Monferrato was dedicated to him as early as 380.
In the context of English educational and legal institutions, Saint Hilary's festival lies at the start of the Hilary Term which begins in January.
