Answer 1

the opening and closing time are saved in Db in Varchar format

That's a big big big mistake. By storing times/dates in anything other than the natural date and datetime types in MySQL, you completely lose the ability to use MySQL's native date/time handling facilities, and will have to do all processing in your client-side code, or write hideously ugly queries to do so in MySQL. Either way, you'll be subjecting yourself to unecessary grief by using varchar instead of date or datetime
