How Long Has Star Been On Earth?

Made a giant list of time markers in EVERY EPISODE, the deleted the ones that didn’t matter so it was shorter and easier to read.

S1E1A Star Comes to Earth: Star’s 14th Birthday, arrives at earth. Whole episode takes place in a single day (1 day)

S1E1B Party With A Pony: Star consider’s Marco a best friend, probably took at least a week ( ≥8 days)

S1E2A Matchmaker: Takes two days total ( ≥10 days)

S1E8A Blood Moon Ball: It’s been 53 days since Tom blew up, and while we don’t know when he last got angry, we do know he got angry in S1E2A Matchmaker. Takes one day and night ( ≥63 days)

S1E8B Fortune Cookies: Probably only takes one day ( ≥64 days)

S1E9A Freeze Day: Takes a single morning ( ≥65 days)

S1E9B Royal Pain: Takes two days ( ≥67 days)

S1E10 St Olga’s Reform School for Wayward Princesses: Probably only takes one day ( ≥68 days)

S1E11A Mewnipendance Day,

S1E11B The Banagic Wand,

S1E12A Interdimensional Field Trip,

S1E13 Storm The Castle: All take one day ( ≥72 days)

Thus, by the end of Season 1, Star has been on Earth for a bare minimum of 72 days, or 2 ½ months, assuming almost no time between many episodes.

S2E1A My New Wand!: Appears to happen directly after Storm The Castle ( ≥73 days)

S2E1B Ludo In The Wild: Ludo spend 90 DAYS (3 months) in the wild before getting his wand, which means next time we see him, at least that much time will have passed. (No star in this episode)

S2E4B Wand to Wand: If we assume both plots happen at the same time, and that Ludo’s plot is almost exactly following his finding of the wand, this is 90 days after Storm The Castle ( ≥162 days! almost 6 months!)

S2E6 Starsitting/On The Job: Ludo already has control of the rats and a harvest-able corn field. The shortest time corn grows (according to google search) is 60 days, so 2 months since Wand To Wand ( ≥222 days; over 7 months!)

S2E7A Goblin Dogs,

S2E7B By The Book,

S2E8A Game Of Flags,

S2E8B Girls’ Day Out: All take one day ( ≥226 days)

S2E9A Sleepover: In theory, could take place the night of the previous episode ( ≥226 days)

S2E9B Gift Of The Card: Takes one day. Confirms Star has been on Earth for over 6 months, but we already knew that at this point -> ( ≥227 days = ≥7 ½ months)

S2E10A Friendenemies: Takes one day ( ≥228 days)\

S2E11A Hungry Larry: If we assume school has been running through-out the season (i.e. no summer break) then this episode’s timing makes zero sense, as it would put Halloween sometime between April and May. Not something to be bugged about as I doubt the directors think too critically about the timeline of the show. ( ≥229 days)

S2E11B Spider With A Top Hat: While I question the canonicity of the actual events inside of Star’s wand, the external events take three days ( ≥232 days)

S2E12A Into The Wand: Takes one day ( ≥233 days)

S2E12B Pizza Thing: In theory, could take place the night of the previous episode ( ≥233 days)

S2E13A Page Turner: Takes one day ( ≥234 days)

S2E13B Naysaya: Takes two to five days, depending on the school day of the episode, as it ends on Friday night. At least two ( ≥236 days)

S2E14 Bon Bon The Birthday Clown: Takes one day. ( ≥237 days)

All this puts the minimum time on Earth as 237 days or 8 months. Assuming, again, that summer break never happens, the maximum time would be 9 months which would put Star’s first day as the first day of school (convenient) and the school dance at the last (probable)
