===Seasonal events===
Tied to the date in real life instead of anything in-game, seasonal events cause changes that aren't vital for game progression but often have exclusive items. Some add enemies/enemy variants, some allow certain enemies to spawn in more places, and two historical ones even had unique bosses tied to them.

Modern versions feature only two seasonal events, both of which can also be manually triggered for an ingame day if certain conditions are met (see Pumpkin Moon and Frost Moon below):
*Halloween - Pumpkins naturally grow without having to be manually planted, Ravens spawn everywhere (not just Graveyards) at night, Ghosts spawn naturally underground, and Hopping Jacks (think big pumpkins that want to kill you) spawn in Hardmode. Enemies drop Goodie Bags with Halloween-themed loot being obtained from them. Some critters and enemies gain Halloween variants, which are basically them wearing costumes. Goes from October 10th to November 1st.
*Christmas - Enemies drop Presents, which contain Christmas-themed loot. Most notable of which is the Snow Globe in Hardmode, meaning the ([[Derp|underdeveloped]]) Frost Legion event is technically locked behind the Christmas season. Some enemies and critters have festive outfits. Goes from December 15th to 31st, and goes out with a bang (literally) by exploding Santa.

Older versions (particularly old console/mobile ones) have a few more:
*Valentine's Day - Worlds generated during this event can contain a Heart Shrine in the Snow biome which allows players to obtain the normally post-Plantera Frozen Biome Chest early - the chest contains several love-themed items (including [[PROMOTIONS|69 coins]]) and the shrine itself also has two Life Crystals which grant 40 extra max HP total. Gems broken during this period have a chance to drop a Cupid pet, and the Merchant sells an accessory and special arrows. Lasts the entirety of February. Still available on Windows Phone and 3DS, with the Heart Shrine oddly only being present on the former.
*Easter - A new enemy, the Diseaster Bunny (ha), spawns if Lepus hasn't been defeated yet. These enemies (alongside Corrupt Bunnies if Lepus hasn't been defeated) are the only way to obtain the Suspicious Looking Egg to summon the boss. Lasts the entirety of April. Still available on Windows Phone and 3DS.
*Thanksgiving - The Merchant sells a pet turkey, and enemies have a chance to drop Cursed Stuffing. Committing animal cruelty using both is the only way to fight Turkor the Ungrateful. Lasts the entirety of November. Still available on Windows Phone and 3DS. (Noticing a pattern yet?)
*St. Patrick's Day - Rainbow pieces fall from the sky during the day (basically Falling Stars but in the sun) and can be crafted into a leprechaun pet. Lasts the entirety of March, and is only still available on Windows Phone (it was never available on 3DS, strangely enough).

A Chinese New Year event was planned for the Mobile version but was scrapped when Re-Logic made the decision to remove content not made by them in the modern console and mobile versions. It would have given the Wyvern a dragon puppet variant among other things.

Several of these removed events, alongside other removed console/mobile-exclusive content, are added back in by mods.
