Holidays are seasonal events in Tomodachi Life. On certain holidays (such as Christmas), there will be food associated with the current holiday available to buy on that day only in the daily specials. After the item has been bought, it will appear in the regular food catalogue.
Japanese version holiday food:
January 1st-3rd: O-sechi (Japanese New year food) Mochi soup (O-souni).
February 3rd: Setsubun Holiday, large sushi roll (ehoumaki) and roasted beans(fukumame)
February 14th: Valentine's Day: Box of chocolates (giri-choco) and hand made chocolate (tetsukuri-choco)
Christmas Day: Roast turkey with all the trimmings.
On the player's birthday, a special event will be held where the player will be presented with a birthday cake by the islanders. This cannot be bought in shops, but will be added to the item list. The player's look-alike will also have a news broadcast with their birthday announced. Other Mii islanders will also have a special news cast broadcast for their birthday, but no cake will be given out.
The birthday song is to the tune of the traditional "Happy Birthday" song with the lyrics changed to "la la la", except the line "Dear [Mii]", possibly because the song is copyrighted.
4th of July: Independence Day (US)
On the Fourth of July, in the American version, the shop interiors will change slightly. For instance, the Pawn Shop has a photo of a hamburger and a hotdog on a red, white, and blue background in the background. Independence Day celebrates the day The US gained its independence from Great Britain, following the Revolutionary War.
