Key dates at a glance
Day of the Dead is fixed to the Catholic liturgical calendar and always follows the same pattern:

| All Hallows’ Eve (Halloween) | 31 October | Not the focus, but part of the three-day sacred season |
| All Saints’ Day | 1 November | Honors all saints; many families visit graves |
| All Souls’ Day | 2 November | Core day for remembering the departed in Mexico |
| Día de Muertos public observance | 1–2 November | Most common community altars and public events occur on these dates |
How Day of the Dead aligns with the Catholic calendar
When is Day of the Dead? It is anchored to fixed liturgical dates: All Saints’ Day (1 November) and All Souls’ Day (2 November). The celebration is not a movable feast like Easter; it always occurs on these Gregorian calendar dates, though local observances can extend into surrounding days with vigils, processions, and offerings. Because the core observance is tied to these saints’ days, the timing remains stable year to year even as secular festivities adapt to weekends and local customs.
Why you may see shifting public activities
Although the religious observance is fixed, public events and school holidays may shift slightly. Communities often schedule parades, market fairs, and cultural performances on the nearest weekend or during a multi-day festival period. This can create the impression that the holiday moves, but the traditional altars and family remembrance remain tied to 1–2 November. Local variations should not be confused with the canonical dates of the feast.
Relationship to Day of the Dead and Halloween
Day of the Dead and Halloween share proximity on the calendar but differ in origin and focus. Halloween (31 October) precedes the solemn liturgical days and is not part of the Mexican tradition. Day of the Dead begins at dusk on 31 October with some community vigils, but the principal family altars and cemetery visits center on 1–2 November. Their closeness can cause overlap in commercial imagery, yet their cultural roots and practices remain distinct.
Regional observance and arrival of community altars
Across Mexico and in diaspora communities, arrival of offerings and public altars often begins on 30 October, with neighborhood gatherings and preparatory work. The most concentrated remembrance occurs overnight between 1 November and 2 November, coinciding with the liturgical days. In some towns, extended festivals may run through early November, but the spiritual core stays tied to the saints’ days and family memory practices.
Relationship to astronomical seasons
Because the dates are fixed in the civil calendar, Day of the Dead shifts relative to astronomical seasons over long cycles due to calendar differences, but within the Gregorian system it stays at the same point each year in early November. This differs from holidays tied to equinoxes or lunar cycles, which can drift across seasons. The stability of 1–2 November makes it a reliable marker in the civic and cultural calendar.
