Overview
- Coverage from Mexican outlets on Thursday through Saturday shows there is no fixed rule for 2026 and that families choose dates based on custom and faith.
- Catholic practice commonly uses the First Sunday of Advent, which falls on 29 November 2026, as a cue to install the tree.
- Another widely used marker is 8 December 2026, the Feast of the Immaculate Conception, which many Latin American households take as a start date.
- Practical guidance stresses safety: place trees away from exits and heat sources to reduce fire and short-circuit risk, and avoid blocking doors.
- Removal customs vary: many take trees down on 6 or 7 January 2027 for Día de Reyes while some families wait until 3 February 2027 after Día de la Candelaria; the practice has roots in older pagan solstice rites and later German and English traditions.
