Between national holidays, saints on the calendar, neighborhood events, and local festivals, identifying what is happening today near you can sometimes be a puzzle. What tools truly allow you to not miss anything, and how do they compare in terms of coverage and accuracy?
Geolocated aggregators and open data calendars: source comparison
Not all information sources on holidays and events cover the same areas. The table below summarizes the main categories of available tools and their characteristics.

| Type of source | Examples | Coverage | Update | Customization |
|---|---|---|---|---|
| Geolocated aggregators | Eventbrite, Meetup, Facebook Events | Participatory events, festivals, workshops | Real-time | “Today” filters, notifications based on location and history |
| Municipal open data calendars | City portals of Paris, Montreal, New York | Neighborhood parties, associative events, municipal festivals | Continuous (open API) | Variable by city |
| Specialized sites for holidays and saints | Saint of the day sites, Catholic agendas | Saints, religious holidays, commemorative days | Annual or fixed | None |
| Official tourist agendas | Tourist offices, parisjetaime.com, bonjourquebec.com | Traditional holidays, public holidays, major cultural events | Seasonal | Low (sorted by month or season) |
The main gap lies between static tools (lists of public holidays, calendar of saints) and real-time aggregators that filter by geolocation. The former answers the question “which saint is celebrated today,” while the latter addresses “what is happening around me tonight.”
To find out which holiday to celebrate today, cross-referencing at least two of these sources remains the most reliable method. A calendar of saints will never indicate the neighborhood celebration three streets away from you, and vice versa.

National holidays, saints of the day, and local events: three distinct streams to monitor
The most common confusion is treating “holidays” as a homogeneous block. In practice, three streams of information coexist without overlapping.
Public holidays and national celebrations in France
France has public holidays divided between civil holidays (January 1, May 1, July 14) and religious holidays (Easter, Christmas, All Saints’ Day). These dates are fixed from year to year, except for Easter and the holidays that depend on it. Public holidays close administrations and schools, but do not always appear in local event agendas.
The saint of the day and associated traditions
Wishing a loved one a happy feast day requires knowing the saint celebrated each day. This information comes from the Catholic liturgical calendar, updated annually. Websites dedicated to the saints of the day remain the most direct source for this specific inquiry.
However, these sites do not cover festivals, associative events, or neighborhood celebrations. A saints’ agenda does not replace an events agenda.
Local events and festivals
This is the most difficult stream to capture. Neighborhood parties, children’s workshops, temporary exhibitions, and local festivals depend on scattered sources: Facebook pages of associations, municipal websites, physical postings. In recent years, several major cities have strengthened their open data event calendars accessible via API, allowing third-party applications to aggregate this information. Montreal, for example, continuously updates a festival guide that centralizes municipal and partner events.
Notifications and geolocated filters: what changes in detecting holidays
Aggregators like Eventbrite, Meetup, or Facebook Events now offer “today” and “this weekend” filters combined with geolocation. Their notification systems leverage participation history to suggest events aligned with the user’s interests.
This personalization represents a shift from static holiday lists. Here are a few criteria to check before relying on an aggregator:
- The actual local coverage: some aggregators are very active in large cities but nearly empty in rural areas. Testing with your own address gives a reliable idea of the density of referenced events.
- The freshness of the data: a canceled or postponed event should disappear quickly. Platforms connected to municipal open data calendars have an advantage in this regard.
- The type of indexed events: Meetup covers workshops and thematic meetings better, Facebook Events captures more neighborhood parties and associative events, while Eventbrite focuses on festivals and concerts with ticketing.
No single tool covers the entire spectrum (saints, public holidays, local events, festivals). The combination of a saints’ calendar, a municipal agenda, and a geolocated aggregator forms the most complete trio.

Recent commemorative days and holidays still absent from classic agendas
Some commemorative days added or reinforced in recent years are not yet included in most holiday articles. These dates can have a concrete impact on local life: closure of administrations, schools, or financial markets.
Classic agendas often reproduce the same list of holidays year after year. New commemorative days sometimes take several years to be integrated into public calendars. This is a real blind spot for those looking to know what is happening today.
To stay updated, institutional portals (government websites, prefectures) are the most responsive source. Aggregators, on the other hand, only reference these days if an associated event is explicitly created by an organizer.
The most effective strategy to not miss anything around you remains to combine three layers: a fixed calendar for public holidays and saints, a geolocated aggregator for local events, and occasional monitoring of municipal or prefectural portals for new official dates. No application yet performs this end-to-end synthesis work.
