When is Immaculate Conception?
In 2026, Immaculate Conception falls on Tuesday, December 8, 2026. It is classified here as a Timor-Leste public holiday.
History of Immaculate Conception
The Immaculate Conception is a major Catholic feast and is recognised by law as the day of Timor-Leste’s patroness. Its national public-holiday status joins a religious celebration to a distinct expression of national Catholic identity.
Parishes mark the day with Mass, prayer and local gatherings. It follows Memorial Day, creating a December sequence in which national remembrance and religious life sit close together in the public calendar.
Immaculate Conception is a national public holiday under Law No. 10/2005 as amended, and the Government’s 2026 notice confirms the date and whether it is fixed or variable. The law generally equates a public holiday with a working day, excuses covered employees from attendance without loss of the corresponding rights, and provides compensation when holiday work is required, subject to rules for shift work and essential public services. A government “day-off tolerance” is different: its beneficiaries and hours follow the particular order and it does not silently create another permanent private-sector holiday. No substitute weekday is assumed unless an applicable law or government decision expressly provides one.
How Immaculate Conception is observed
A national public holiday on December 8. Government tolerances and local holidays are separate, notice-specific measures and should not be inferred from this national date.
