Seasonal events

Seasonal events are annual occurrences activated depending on the platform/device's date setting. While active, a seasonal event may offer new season-appropriate items or character spawns.

Tips

 * All seasonal events can be "activated" by setting the device's date to any date within the respective event's timespan.
 * Change the computer's date to any day within the timespan.
 * If changing the computer's system date is not desired, applications like RunAsDate (Windows) or faketime (Linux, macOS) can launch Terraria with a specific date.
 * Disconnect from Xbox Live /  PSN and change the console time.
 * Disconnect from automatic date/time updates and set the time to any day within the timespan. Note that this does not work for some devices.
 * Go to "System Settings" and set the date there.
 * Completing the Pumpkin Moon or Frost Moon event will also unlock the Halloween or Christmas seasonal event for one in-game day.
 * All 3DS Seasonal Events are also on Windows Phone.
