* ''Christmas [=NiGHTS=] into Dreams...'' was a one-level demo of ''VideoGame/NightsIntoDreams'' for the UsefulNotes/SegaSaturn, with the main differences being a change of graphics and models based on the time of year and a small Christmas-themed side story that supposedly takes place after the events of the main game. Despite being only a demo, it has additional features unlocked when a save file of the original game is present. One of the fan favorites was on April Fools' Day, where Reala's character model would replace that of [=NiGHTS=]. ''Christmas [=NiGHTS=]'' later reappeared as an extra in the UsefulNotes/Playstation2 port of the original game.

* After beating ''VideoGame/{{D2}}'' and sitting through the end credits, a clock appears counting down to (or the time past) December 31, 1999. If the player alters the [[UsefulNotes/SegaDreamcast Dreamcast]]'s internal clock so that this post-credits display reaches midnight on New Year's Day, it triggers the message "Welcome to the 21st Century!" Not only that, but if you try to play a Dreamcast demo disc from the official magazine around Christmas the background will be Christmas-themed.

* Turn on a UsefulNotes/NintendoDS on your birthday (which you can input into its memory) and you get a special activation jingle, as well as a birthday notification in [=PictoChat=]. Sadly, the [=DSi=] does not do this. Photos and videos made with the [=3DS=] Camera on the set birthday will be put under a heading marked with a cake instead of the numerical date.
* Log into a UsefulNotes/WiiU on your birthday (again, you can input this), and you will hear some chimes while the crowds of Miis run in with arms raised.

** ''VideoGame/PokemonSleep'' introduces a week-long event centered around the holidays. They typically take place on Greengrass Isle and is themed for the holiday taking place. The Halloween event played a spooky remix of Lavender Town’s theme and introduced the Shuppet line to the game.

** Mt. Silver in ''[[VideoGame/PokemonGoldAndSilver Pokémon HeartGold and SoulSilver]]'' also features Diamond Dust on certain days, including the release date of the original ''Gold and Silver''.

** ''[[VideoGame/PokemonGoldAndSilver Pokémon HeartGold and SoulSilver]]'' do this as well, by talking to Ethan or Lyra.

** ''VideoGame/PokemonXAndY'' has the Pokémon Center greet you with a surprise party and a birthday cake on the screen above the front desk. It also switches the music to a music box version of the Pokemon Center theme and Nurse Joy greets you with a happy birthday. Your birthday is also the only time you can obtain Supreme Wish [=PokéPuffs=] in Pokémon-Amie. Additionally, the Diamond Dust can be seen in the Frost Cavern area north of Dendemille Town.
** ''[[VideoGame/PokemonRubyAndSapphire Pokémon Omega Ruby and Alpha Sapphire]]'' do the same thing as ''X and Y'' on the player's birthday. The Japanese version of the games also play "HappyBirthdayToYou" when entering the Pokémon Center, but this had to be changed for the international versions due to the song still being copyrighted at the time, but luckily this ended up quickly being reverted after the song became public domain.
