1337 hour (pronounced Leet Hour) is the time when everyone should stop what they are doing and do something elite. Leet hour is 1:37PM which originates from 1337 or 13:37 military time. It's important to note that 1337 hour is not actually an hour but rather a minute, from 13:37 to 13:38. It is referred to as 1337 hour because actions performed during that minute are more epic than normal actions that actually take hours.
