Simplify the following text for a Grade 6 native English-speaking person.
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 .
