thanks ery much i will try it. but i unified the format and problem solved

hello i have the following condition inside an if but something is wrong because i get different output from what i expect i'm comparing a database table record fields with a user input datathe the database table record fields representing a busy slot are saved into variables as follows: $UnSlotDay: the day name $UnSlotStartTime: busy slot start time $UnSlotEndTime: busy slot end time the user input for a new slot is: $Day: the day name $EndTime: new slot end time $StartTime: new slot start time if (($Day == $UnSlotDay) && (($EndTime<=$UnSlotStartTime) || ($StartTime>=$UnSlotEndTime))) echo "OK"; else echo "Not OK"; if the busy slot is on Monday from 09:00:00 to 11:00:00, and the the new slot is also on Monday from 11:00 to 12:00 I get the message "Not OK". Is it because the user input in hh:mm format and the busy slot is in hh:mm:ss ??? pls help me
