有關GRAMMER 問題

no need to add 'on'

last Friday already means on the Friday in the previous week

you only need to add 'on' when you say: I went to xxx on Friday(s).

you also don't need to add 'on' before 'every', like:
I went to xxx on every Friday. <--wrong
I went to xxx every Friday. <--correct

唔洗　　因為要係一ｄ特定既時間　　先要加in on at the

發問者 : 不需要加 on -------> I want to XXXXX last Friday.
