A time zone is a standard time used in a geographic area. It's the time we've all agreed to follow so it's easier to travel, communicate and barter with people around the world.

These lines aren't straight and neat, many are negotiated and agreed based on the country's needs.

Pacific Time Zone (PT) consists of places that use:

• Pacific Standard Time
• Pacific Daylight Time

Pacific time zones can either be Standard or Daylight depending if the region using the zone observes daylight savings time during spring and summer seasons.

Pacific Standard Time or PST for short is 8 hours behind Coordinated Universal Time (UTC - 8:00). During the months when daylight savings is observed, Pacific time zone changes to Pacific Daylight Time or PDT which is 7 hours behind Universal Time (UTC -07:00).

This means that the time zones leveraged in pacific time zone regions are 8 places behind the starting line of Greenwich.
