Scheduling

Scheduling is the division of time into a set, understandable (and therefore predictable and actionable) measurement and/or sequential or organizational structure. Scheduling can be done in many different ways, as different cultures have vastly different ways of experiencing, interpreting, measuring and denoting the passage of time as well as how they valuate the issue of timeliness (and tardiness). For this reason, many different Calendar systems and date/time formats have emerged.

Scheduling in most modern computer systems is based on the Gregorian Calendar, which involves dividing up the year's 365 days/12 months/52 weeks by the respective 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).
