In addition to the other answers  there is also the TimeUnit class which allows you to convert one time duration to another  For example  to find out how many milliseconds make up one day   TimeUnit MILLISECONDS convert 1  TimeUnit DAYS     gives 86400000   Note that this method takes a long  so if you have a fraction of a day  you will have to multiply it by the number of milliseconds in one day

The best practice for this  in my opinion is   TimeUnit DAYS toMillis 1          1 day to milliseconds  TimeUnit MINUTES toMillis 23      23 minutes to milliseconds  TimeUnit HOURS toMillis 4         4 hours to milliseconds  TimeUnit SECONDS toMillis 96      96 seconds to milliseconds

Its important to mention that once in 4-5 years this method might give a 1 second error  becase of a leap-second  http   www nist gov pml div688 leapseconds cfm   and the correct formula for that day would be   24 60 60   1    1000   There is a question Are leap seconds catered for by Calendar  and the answer is no   So  if You re designing super time-dependant software  be careful about this formula
