Urgent reply needed please

I prepared 3 cheques; 2 for cash and one payable to a company but the date I sort of messed up on the cheque for like 2 days ago..today is the 22nd of March, date on cheque for 20th March. Do I have to cancel these cheques and prepare new ones? Its just earlier dated, that shouldn't be much of a problem right? I'll be cashing the 2 cheques at the bank today and the third one will be paid to a company next week.

Thanks so much in advance. I'm a finance intern btw :3
