Ascension Day always falls on a Thursday; it is the fortieth day after Easter Sunday so can fall anywhere between 30th April and 3rd June. Rogation Monday and Tuesday, and Ascension Eve are the days leading up to Ascension Day. This period is traditionally associated with boundary checking, walks and processions.

Whitsuntide is a festival commemorating the descent of the Holy Spirit on the Disciples. It is the seventh Sunday after Easter so varies in date, always falling between mid May and mid June. Because it is easier to plan events for a fixed date each year, many former Whitsuntide events have been moved to Spring Bank Holiday instead. Trinity Sunday is the Sunday after Whitsun and celebrates the Christian doctrine of the Trinity (God the Father, God the Son and God the Holy Spirit) ;  Corpus Christi is the Thursday after Trinity and honours the body of Christ. In the UK this was a major festival before the Reformation but is now comparatively little known outside the Roman Catholic Church.
