The Seoul Metropolitan Fire and Disaster Headquarters will begin selling its 2025 calendar featuring muscular Seoul firefighters from Saturday until January 19.

The annual steamy calendars have grown in popularity since they were first released in 2014, with all proceeds from the sales being donated to burn patients who need help with their medical expenses.

This year, a portion of the proceeds will be specifically allocated to support a ten-year-old burn patient, according to the fire headquarters.

To date, a total of 110 thousand calendars have been sold, raising one-point-one billion won, or over 793 thousand U.S. dollars, and providing financial support for 260 burn patients.

Three different calendars will be available for 2025 and can be purchased from GS Shop and the online mall 10x10.
