Difference Between PDT and EST (With Table)

The PDT and EST are time zones in the Eastern and Pacific parts of the globe. Both these time zone have their different timings according to the Universal time. Both these times are calculated by keeping in mind the universal time. The PDT and the EST are not at all the same. This should be noted by every individual.

PDT vs EST

The difference between PDT and EST is that the timing of PDT is the short form of Pacific daylight timing which is seven hours before the universal timing of the world, and on the other hand, the EST is the short form of Standard eastern timing, which is five hours before the universal timing.

The PDT that is the Pacific Daylight Timing is the timing which is usually seven hours behind the GMT. This timing is usually followed in the months of summer, where the PST (Pacific standard timing) is followed in the world. This PDT timing is followed in THE United States, Mexico, and Canada, just like in PST.

The EST that is the Eastern Standard Timing is the timing which is usually five hours before the UTC. This is the zone of timing which is used in all part of the eastern parts of the world. This zone of timing falls off in the winters where the EDT eastern daylight timing is followed in the world.

What is PDT?

The PDT that is the Pacific Daylight Timing is the timing which is usually seven hours behind the GMT. This timing is usually followed in the months of summer, where the PST (Pacific standard timing) is followed in the world. This PDT timing is followed in the United States, Mexico, and Canada, just like in PST.

In following a time zone, the PDT (Pacific Daylight Timing) is just another way of the PST. This timing zone started in the middle of March and came to an end, usually by the end of November. The timing periods are not that approximate, but yes, it is somewhere around it.

This time zone makes observed in summer, which makes the day even longer. The standard timing of PDT ( Pacific daylight timing) is one hour more than that of PST ( Pacific standard timing). The PDT timing is set back with the PST timing on the first Sunday of November. Earlier, this change was on the first of April, but now the policy was changed by the government.

What is EST?

The timing of PDT that is Pacific daylight timing, is usually five hours before the UTC. This is the zone of timing which is used in all part of the eastern parts of the world. This zone of timing falls off in the winters where the EDT eastern daylight timing is followed in the world.

The EST (Eastern Standard Timing) is replaced from the EDT (Eastern Daylight Timing) on the second Sunday of November. The eastern daylight timing is one hour ahead of the Eastern Standard timing. An international Conference is usually set between any time from 10 am to 6 pm, when the Eastern Standard timing is taken into consideration.

On the second of March, the Easter standard timing is switched back to the Easter Daylight timing. This timing is the countries of North America, Central America, and the Caribbean. There is a gap of one hour when the Eastern daylight timing and Eastern Standard timing get replaced with each other.

Main Differences Between PDT and EST

  1. The full form of PDT is Pacific daylight Timing, and on the other hand, the full form of EST is Eastern standard timing.
  2. The PDT (Pacific daylight timing) is seven hours before the Universal timing (UTC), and on the other hand, the EST (Eastern standard timing) is five hours before the Universal timing (UTC).
  3. The PDT (Pacific daylight timing) timing is seen in the months of summer in the year, and on the other hand, the EST (Eastern standard timing) timing is seen in the months of winter in the year.
  4. The PDT (Pacific daylight timing) is observed in all the northern parts of the world, and on the other hand, the EST (Eastern standard timing) is observed in all the Eastern parts of the world.
  5. The PDT (Pacific daylight timing) comes into effect from the first Sunday of November, and on the other hand, the EST (Eastern standard timing) comes into effect from the second Sunday of November.

Conclusion

There are over 25 different timing zone all around the world. The PDT (Pacific daylight timing) and the EST(Eastern Standard timing) are two of these different timing zones which are observed in the northern and eastern parts of the world, respectively. The PDT and the EST have a gap of two hours between them. The PDT arises first when compared to EST.

A person should have general knowledge of the difference between these timing zones. This would make it easier for a person to calculate the timings of different countries and convert them. If it is 2 pm in PDT timing, then it will be 4 pm in EST timing.
