Full Moon
We're not currently in a full moon.
The next full moon is from December 21, 2018 at 7 AM through to December 23, 2018 at 7 AM (UTC).

The Full Moon restriction was introduced with the 2011 Very Scary Halloween Special. All previous items that were restricted to Halloween were updated to be equipable during both Halloween events and full moons. These items are available for use during full moons according to a formula that approximates the lunar calendar. During this period, the main menu background will become a full-color image of Double Cross, the menu class portrait will sometimes wear their Halloween Costumes, the default Message of the day will state "Welcome and Enjoy the Full Moon!", and Strange weapons equipped with Strange Part: Full Moon Kills will count kills performed during this timespan.

When the Full Moon restriction was introduced with the 2011 Very Scary Halloween Special, the formula was set such that the Full Moon event occurred every 29.5 days starting Midday, October 12, 2011. The periods lasted for a full day before and after the time calculated, so the very first Full Moon event was one day either side of 12am (Midnight) on November 10, 2011. However, the actual synodic month is close to 44 minutes and 3 seconds longer than the 29.5 day approximation. The effect of this was that after about four years, the TF2 Full Moon schedule was about one and a half days ahead of the actual lunar phase -- by June 2, 2015, the game (and the Fmp calculations at that time) would close Full Moon events hours before the real Moon was actually full. However, by September 2015 and in subsequent months, the in-game Full Moon event was observed to be more centered on the real full moon time, indicating that the previous game schedule had been changed. The formulation computing the Full Moon dates for this page was changed in November 2015 to more closely track the observed Full Moon events.

All times on this page are in Coordinated Universal Time (UTC).
