Many Argentinians are already looking at the calendar to organize getaways, family gatherings, and the first preparations for the holidays. December brings two key dates that close out 2025 with rest and celebrations, and one of them creates a long weekend.
The last month of the year includes the last national holidays and offers an ideal break before Christmas. Below is the updated detail to plan ahead.

The next holiday: Monday, December 8
The first holiday of the month is Monday, December 8, the Day of the Immaculate Conception of Mary. This is a non-movable holiday established by Law 27.399.
Since it falls on a Monday, it creates a three-day long weekend, perfect for those seeking a short getaway.
A key date for Argentinian families
In addition to its religious significance, December 8 is an iconic tradition in the country. It is the day when hundreds of families set up the Christmas tree, marking the start of the festive season.

The other holiday of the month: Christmas
The second and last holiday in December arrives on Thursday, December 25, the day Christmas is celebrated. It is also a non-movable holiday and one of the most significant of the year.
Although it doesn't create a long weekend, it remains a day for family gatherings, rest, and celebrations throughout the country.

What about Christmas Eve?
December 24 is not a holiday, but in many workplaces the workday is shortened or there is no work at all. Something similar happens on December 31, when businesses and agencies close early for New Year's Eve celebrations.
What happens next: the first holiday of 2026
The next national holiday will be January 1, 2026, for New Year's Day. On that day, most businesses and banks operate with special hours or do not open at all.
