grammar check, please correct if I am wrong

It's a rule which is often taught in EFL classes but it refers specifically to sentences like "It was my birthday yesterday" in contrast to "It was my birthday on Thursday". It doesn't apply, of course, in cases like "From tomorrow, no books may be taken out of the library." or "I didn't know about that rule until yesterday". (Actually, the sentence "In general I know that a preposition is not used before yesterday" is quite amusing because 'before' is actually a preposition!)

@owlwings "from tomorrow" seems to be uk english. i would mostly likely use "starting tomorrow" or "from now on"

@hereandthere There is only one English, the UK English, the other language is American.

but online source says that ON should not precede YESTERDAY, can you explain since u are US citizen

@Manasha Nope. Can't explain. But using ON is the correct way.

@minx267 Using On is the correct way.

Well said. I'm glad English is my first language.. it sounds to complicated to have to learn.

@LadyDuck @Manasha is correct in thinking that "I visited my aunt on yesterday" would be incorrect, whereas "I visited my aunt on Thursday" would be correct but the confusion has arisen because the possessive case of "yesterday's" (in both your example and his/hers) means that it is being used as an adjective and replacing "yesterday's" with the definite article should make it clear that "on" is the appropriate preposition. A simple analysis of what words belong to what other words might go something like this: "Please share your feedback" What feedback? "The feedback on the visit" What visit? "Yesterday's visit" Put all the information together. "Please share your feedback on yesterday's visit."

@owlwings Thank you very much for this interesting lesson. In fact the confusion has arisen because of the use of the possessive case.
