Synopsis
Twelve best friends living in an alternate Earth where months, holidays and other time and date-related stuff are humanoids (while also living in peace with normal humans) like to make the most of every day despite their colliding personalities, which can result in lots of wacky situations along the way, all in the fictional city of Calendarwood.

Main

 * January (voiced by Alanna Ubach) - a sad and sensitive teenage girl who thinks everything is meaningless, but is often comforted by the months and finds them as her "family".
 * February (voiced by Greg Cipes) - a matchmaking and romance-loving teenage boy who loves to pair people with someone, and is considered as a "secret cupid".
 * March (voiced by James Arnold Taylor) - a clean-freak and perfectionist teenage boy who wants everything clean and perfect, even whining when a single tiny drop gets on a floor in his path. Despite this, however, he deeply cares for his pals.
 * April (voiced by Tara Strong) - a naïve and airheaded but friendly teenage girl who is very curious and wants to know how it is, while also can be stupid at times. Despite this, however, she is a kind person and wants to make those who have upside down faces happy.
 * May (voiced by Steve Blum) - a geeky teenage boy who loves movies, especially science fiction movies. However, he dislikes being called May, finding it as a girly name and prefers to be called Matt.
 * June (voiced by ) - a very chill teenage boy who likes to talk smoothly and often is willing to help people with their problems.
 * July (voiced by Grey DeLisle) - a fun-loving, clumsy and party animal yet a wet blanket teenage girl who loves having fun, and even throws parties. But she is very clumsy, and her clumsiness can start problems and tends to be a wet blanket at times.
 * August (voiced by Josh Keaton) - an easily bored teenage boy who finds almost everything boring, but owns a pet cat named Frost, which makes him smile.
 * September (voiced by Eric Lopez) - a snarky, feisty and short-tempered teenage boy who gets annoyed by his pals' antics, especially November's vain-ness. Despite that, if he sees his friends in trouble, he will show the one that's attacking them no mercy.
 * October (voiced by Rachael MacFarlane) - a cynical and emotionless, yet scary loving teenage goth girl who is usually emotionless and doesn't react to anything, but does ADORE anything scary. She also has a very sweet tooth, loving to eat candy.
 * November (voiced by Vanessa Marshall) - an extremely vain and seductive, but thankful teenage girl who is the most beautiful of the gang, but loves her own looks, to the point where she will whine and cry if she gets ruined, even if a SINGLE tiny drop touches her or her clothes. Despite this, she is very thankful and deeply cares for her friends, even calling them her "sibling-figures".
 * December (voiced by Jennifer Hale) - an optimistic and happy-go-lucky mismatched eyed teenage girl who LOVES anything snowy and holiday-related, and even has a habit of giving everyone, including strangers, gifts.

Supporting

 * Father Time (voiced by Joe Alaskey) - the wise and caring man who is considered by many to be the "king of time" who the months consider him to be a "father figure" to them, living in the same place as the months as he wants to make them safe.
 * Mother Nature (voiced by Jennifer Martin) - a wise and calm woman who cares about the environment around the planet and actually has the ability to control it, and also despises pollution.
 * St. Newyear (vocal effects by TBD) - the months’ pet cat who can act as emotional support to January alongside the other months whenever she feels down.
 * Katrina Adams (voiced by TBD) - a popular teenager known for being ditzy and slightly weird as she ends up befriending November, often getting in misadventures with her.
 * Phoebe Moon (voiced by TBD) - a fashionista and snobby, yet friendly teenage girl who is December's close friend, often letting December be her model and trying out her fashion.
 * St. Patrick (voiced by Rodger Bumpass) - a goofy and crazy leprechaun who also loves gold as he finds March and often annoys him, much to his chagrin.
 * Cupid (voiced by Kaley Cuoco) - a giddy and insane embodiment of love who has a massive and slightly stalkery crush on February as she can sometimes be too creepy.
 * Anderson Fents (voiced by TBD) - a geeky teenage boy who is a huge fan of movies, and quickly becomes May’s best friend and movie watching buddy.

Antagonists

 * Mr. Anton Peterson (voiced by TBD) - a rude neighbor to the months who finds them to be weird and menaces as he often tries to set up traps to catch them.
 * Death (voiced by TBD) - a sinister and menacing supernatural figure in a dark hoodie who is rather intimidating and is often the cause of some of the chaos the mains deal with.
 * Sr. Funtime (voiced by TBD) - a seemingly wacky and innocent man who is secretly an awful person and wants the months gone from his sight, no matter what it takes.
 * Giselle and Melanie Swiningham (voiced by TBD) - a rude and manipulative fashion mogul and her seemingly equally snobby model daughter who seem to be in it together as it is eventually revealed that Giselle is manipulating her own daughter thanks to the months helping a sad Melanie exposing the truth.

Scrapped theatrical movie
In 2006, the same day as the then-renewed season would be the last, Warner Bros. announced that they are planning a theatrical movie to Yearly Adventures, which would end up serving as a de-facto series finale, originally planned for a 2008 release.

However, the movie eventually got scrapped due to budget constraints and also never exited pre-production. Despite this, the movie script, which would've revealed the name as The Yearly Adventures Movie was eventually leaked online sometime in April 2023, and the creator Lauren Faust stated that she'd love to bring back the original plot of the movie for something else Yearly Adventures-related, but said she's "unsure when".
