PST and EST are time zones in North America. PST is Pacific Standard Time and EST is Eastern Standard Time. There is a difference of 3 hours between these time zones. The Timezone Offsets of PST and EST are -8 and -5 respectively. This means that PST is eight hours behind Coordinated Universal Time (UTC), while EST is only five hours behind.
When considering the difference between EDT and EST, we need to understand how Daylight Saving Time functions. In the summer, those who observe this practice will be on EDT time which is four 4 hours behind Universal Coordinated Time. During the winter months when they go back an hour, they will be 5 hours behind UTC and therefore part of Eastern Standard Time.
