Everyone messes up the first timesheet. I once typed “5:00 PM” as “5:60 PM.” Yes, I invented a 60-minute hour. Excel did not laugh. It just showed an error that looked like a crying robot.
Another classic: forgetting the colon. Typing “900” instead of “9:00” turns your timesheet into a flat number. Your boss will think you worked 900 hours. That’s a fun conversation.
