Original: A typical usage is giving opening hours ending at midnight , e.g. '' 00:00 â '' 24:00 '' , '' 07:00 â '' 24:00 '' . Similarly , some railway timetables show 00:00 as departure time and 24:00 as arrival time .
Simplified: For example , you would say '' Tuesday at 24:00 '' and '' Wednesday at 00:00 '' to mean the exact same time .
