Winter Field Day is an annual event organized by the Winter Field Day Association (WFDA) for amateur radio enthusiasts. It's designed to encourage emergency communications preparedness among amateur radio operators. Participants set up temporary stations in various locations, often in challenging winter weather conditions, to demonstrate their ability to operate in various environmental settings and conditions.

The event is similar to the more well-known Field Day in summer, organized by the American Radio Relay League (ARRL). During Winter Field Day, operators attempt to make as many contacts as possible, using different modes of transmission and bands, enhancing their skills and readiness for emergency situations.

Winter Field Day in 2024 is scheduled for January 27th and 28th. This event is held on the last full weekend of January each year. It's a 24-hour exercise starting from 1900 UTC on Saturday and ending at 1900 UTC on Sunday. Participants can begin setting up their stations no earlier than 1900 UTC on the Friday before the event.
