About this calculator
The Brazilian Commemorative Dates Calculator lists the main Brazilian holidays and celebrations for a specific month of the year. Simply select the desired month, and the tool displays national holidays, cultural dates, religious events, and other important occasions in the Brazilian calendar. It is useful for planning events, trips, or seasonal campaigns.
The tool works from a curated database that associates each month with its most relevant commemorative dates in Brazil. No complex calculations: the system queries the database and returns the dates in chronological order, with a brief description of each. Data follows official sources and widely recognized calendars.
Use this calculator when you need to organize for Carnival, Mother's Day, June festivals, Christmas, or other celebrations. It helps teachers plan school activities, marketers create seasonal campaigns, and anyone who wants to know which important dates fall in a month. Ideal for avoiding surprises and making the most of the calendar.
Caution: commemorative dates may vary from year to year (such as Carnival, which depends on Easter). The calculator considers the current year, but always check the exact date from official sources for movable events. Additionally, the list does not include municipal or state dates, only those of national scope or widely celebrated.
