on or before vs on and before

Both "on or before" and "on and before" are correct, but they are used in different contexts. "On or before" implies a deadline or a date range that includes the specified date. However, "on and before" implies a specific date that is included in the range. The choice between the two depends on the specific meaning you want to convey.
