The PDT and EST are time zones in the Eastern and Pacific parts of the globe. Both these time zones 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. Every individual should note this.
Key Takeaways
- PDT stands for Pacific Daylight Time and is used in the western part of North America, while EST stands for Eastern Standard Time and is used in the eastern part of North America.
- PDT is three hours behind EST, so when it is 9:00 am in New York (EST), it is only 6:00 am in Los Angeles (PDT).
- PDT is used during the summer months when daylight saving time is in effect, while EST is used during the winter months when daylight saving time is not.
PDT vs EST
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, EST is the short form of Standard eastern timing, which is five hours before the universal timing.
The PDT is the Pacific Daylight Timing, which is seven hours behind the GMT. This timing is followed in the summer when the PST (Pacific standard timing) is observed worldwide.
This PDT timing is followed in THE United States, Mexico, and Canada, just like in PST.
The EST is the Eastern Standard Timing, which is five hours before the UTC. This is the zone of timing used in all parts of the eastern parts of the world.
This timing zone falls off in the winter when the EDT eastern daylight timing is followed worldwide.

What is PDT?
The PDT is the Pacific Daylight Timing, which is seven hours behind the GMT. This timing is followed in the summer when the PST (Pacific standard timing) is observed worldwide.
This PDT timing is followed in the United States, Mexico, and Canada, just like in PST.
Following a time zone, the PDT (Pacific Daylight Timing) is another way the PST. This time zone started in the middle of March and came to an end, 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 ( Pacificexpectedd timing).
The PDT timing is set back with the PST timing on the first Sunday of November. This change was on the first of April, but now the government has changed the policy.
What is EST?
The timing of PDT, which is Pacific daylight timing, is five hours before the UTC. This is the zone of timing used in all parts of the eastern parts of the world.
This timing zone falls off in the winter when the EDT eastern daylight timing is followed worldwide.
The EST (Eastern Standard Timing) is replaced by 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 set between 10 am to 6 pm when the Eastern Standard timing is considered.
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 Eastern daylight timing and Eastern Standard timing get replaced with each other.
Main Differences Between PDT and EST
- The complete form of PDT is Pacific daylight Timing, and on the other hand, the entire state of EST is Eastern standard timing.
- The PDT (Pacific daylight timing) is seven hours before the Universal timing (UTC). On the other hand, the EST (Eastern standard timing) is five hours before the Universal timing (UTC).
- The PDT (Pacific daylight timing) timing is seen in the months of summer the year; on the other hand, the EST (Eastern standard timing) timing is seen in winter.
- 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.
- The PDT (Pacific daylight timing) comes into effect from the first Sunday of November; on the other hand, the EST (Eastern standard timing) comes into effect from the second Sunday of November.
