My favorite holiday is probably Passover, it lasts eight days and during those eight days you can't anything that has grain in it, It's to celebrate when God led the Israelites out of Egypt. It also is really fun because you get to have a sadder dinner with lamb, you get presents and you get to do other fun stuff. is kind of like the Jewish version of Christmas in a way. It is a very special holiday to me and I look forward to all year.

Does this paragraph have three prepositional phrases in it and is it Grammarly correct

I see comma splices, omitted words, second person, spelling errors.

Have someone read it aloud to you. The two of you will quickly find the places where you have omitted words and have spelling errors. The two of you should also be able to figure out when one sentence ends and the next begins -- and put proper punctuation and capitalization in the right places.
