i don't know

Are we still having the seminar on 1st April? At what time? I want to say, I don't know if it was cancelled or changed to another date. I need to know what time it will be. Thank you. The changes I made: still instead of definitely intend to convey - I want to say your another date (that is grammatically wrong)- to another date And I need to know (a sentence should not begin with "and")- I need to know Hope this helps :)

Are we still having the seminar on 1st April? What time?|What time it is going to be?(timing does not suit here, timing is more like the control or speed or something) I intend to convey I don't know if it was cancelled or changed your another date.(you can convey the message; I think convey is more like to carry or to take from one place to another..So maybe a better way to use the verbs "say, inform" And I need to know what time it will be.(Besides, I need to know what time it will be) Thank you

Just 3 small changes! Are we still / definitely having the seminar on April 1st? What time? I intend to convey I don't know if it was cancelled or changed to another date and I also need to know what time it will be. Thank you
