Not-So-Forgotten Birthday
aka: Forgotten Birthday

Timmy: Don't worry about forgetting that my birthday was today, Mom and Dad. It's OK.
Dad: What?! Forgot your birthday?
Mom: We'd never forget your birthday, Tommy!

A major character is sure everybody's forgotten his or her birthday (or perhaps a similar occasion) and wanders around in an angry funk until surprise! They not only remembered it, they threw a Surprise Party!

The instigating factors in this plot are often that the character who is having a birthday often never actually comes out and says that it is their birthday ("Hey, guess what day it is?" or "Isn't today a special day?"), and the other characters further complicate by answering ambiguously ("Seems like any other day to me.")

These sorts of plots are fueled by Poor Communication Kills and often have shades of Idiot Plot because they could be resolved by one of two simple actions. Main Character: "Hey, it's my birthday!" or Supporting Character: "Happy Birthday, [character]!" then saying they simply hadn't heard anything about a party yet. However, then there wouldn't be much episode to be had.

A subtrope of Birthday Episode. May overlap with The Complainer Is Always Wrong. For the version about the birthday of a marriage (anniversary), see Forgotten Anniversary.

If the birthday is truly forgotten, or if nobody cares about it, it may lead to One-Person Birthday Party. Contrast Ironic Birthday, when the birthday character is stressed or depressed about something other than their surprise party.

  • Mai-HiME episode 10. Made somewhat more surprising for the audience (and thus less Anvilicious) by not revealing what exactly Mai is upset about until the very end.

Nagi then manages to call her back for the actual party.
  • Played for Drama in one episode of Sailor Moon S, used to facilitate Chibiusa/Rini's Face–Heel Turn.

She's convinced it's just a lie and it doesn't work.

At the same time, he was disappointed that she didn't seem to remember it herself.

    • Apparently Mochizou has a drawer full of presents he has failed to give Tamako, though it's not obvious how much of that is due to forgetting instead of the obvious nervousness.

    Comic Books 
  • This happens to Donald Duck in "The Duck that Never Was", a Don Rosa comic story celebrating the 60th anniversary of Donald's creation.

  • A Little Archie Comics story presented a subversion of this. Veronica tells Archie that she thinks her dad has forgotten it's her birthday - and he has, because he's busy making plans for next week's Founder's Day celebration.

When Rocket finds and opens the chest, a birthday cake rises out, and the other Guardians emerge from the shadows to wish him a happy birthday. Rocket actually bawls from disappointment, since the chest didn't have money inside.

  • In one episode each of Captain N: The Game Master and the children's program Today's Special, a character (Mega Man and Scott the living mannequin, respectively) feels left out because they are not truly alive and therefore cannot have a birthday.

That, among other things, was held by Jorgen as a reason to believe Timmy would still need fairies.

Notably, this plot isn't the whole focus of the story, but instead sets up the circumstances that allow the evil Purple Pieman to force the kids to give him all their berries (he sells them a magic watering can they give to her as a gift — it appears empty but generates water when you tip it. It's just that he's the only one who knows how to stop the flow...)
