When is Assumption Day?
In 2026, Assumption Day falls on Saturday, August 15, 2026. It is classified here as a Monegasque public holiday.
History of Assumption Day
The Assumption of Mary is a legal paid public holiday in Monaco on August 15. Catholic teaching celebrates Mary’s being taken into heavenly glory, and the feast occupies an established place in the Archdiocese’s summer calendar. Unlike Monaco’s patronal feast of Saint Devota, Assumption is part of the broader Catholic calendar, but it remains one of the twelve legal holidays expressly published for the principality’s employees.
Monaco Cathedral and parish churches schedule Masses and offices for the feast. In 2026 the cathedral programme included French, English and Italian services, reflecting the principality’s international worshipping community, as well as lauds and vespers. Individual parishes may also organise a Marian procession, but there is no single obligatory state procession covering the whole country. August tourism and holiday travel mean that venues and transport can follow special seasonal schedules in addition to legal closure rules.
Monaco’s Law No. 800 makes the legal holidays in Law No. 798 compulsory paid non-working days for employees, subject to the law’s stated exceptions. Payment is also protected when the date meets an employee’s weekly rest day or a day normally not worked. The annual Labour Directorate circular supplies the operative calendar and reports a fixed holiday falling on Sunday to Monday; it does not create a general Saturday-to-Monday transfer.
