Timeline of the show doesn’t make sense

Like at all. The show starts with Madeline finding out she’s pregnant (let’s say she’s about two months along) and in S3E1 she gives birth. This means about 7 months should’ve passed. However it’s always super sunny, they’re always wearing summer clothes (never big winter jackets or sweater). Then there’s also the fact that in S1 they go to this fancy restaurant with Randy Zimmer. Emily is told she made a reservation for the 8th of November and not the 11th of August but then in S3 Mindy talks about “La fête de la Musique” which is celebrated on the 21st of June.

Did no one from the actors or writers or producers see how wrong their timeline is? 😂
