Scheduling involves dividing up the 365 days/12 months in a year, 28-31 days per month, and 24hrs in per day into timeslots, within which to place various meetings, arrangements, appointments and plans. In computer systems, schedulers can run repetitive tasks (as in a daily back up) to save time from perform tedious daily activities.

Timezones

Differences in timezones typically need to be taken into consideration in scheduling people (and possibly even machines/server) for performing a certain activity (such as participating in a conference/meeting, or, crunching some important numbers or fetching some data).
