CDT vs PDT: Difference and Comparison

CDT stands for central daylight time, used by most of the zones during summertime which is approximately five hours behind the UTC.

PDT stands for pacific daylight time, which is also used by many countries and is about seven hours behind the UTC. That is coordinated universal time.

Key Takeaways

1. CDT stands for Central Daylight Time, the time zone used in parts of North America during the summer months, while PDT stands for Pacific Daylight Time, the time zone used in parts of North America during the summer months.
2. CDT is one hour ahead of Central Standard Time, while PDT is three hours behind Eastern Standard Time.
3. CDT is observed in parts of the United States, Canada, and Mexico, while PDT is observed in parts of the United States and Canada.

CDT vs PDT 

CDT (Central Daylight Time) is observed during the summer months in regions located in the central part of North America and is six hours behind Coordinated Universal Time. PDT (Pacific Daylight Time) is observed during the summer months in regions located in the western part of North America.

Most global zones use central daylight time during the summertime. The largest city that falls under the central time zone is Mexico City. Mexico is the largest metropolitan city in the area and North America.

The pacific daylight time is the time zone used in North America and is about seven hours behind the coordinated universal time. For example- New York is currently on the 74th-degree longitude on the west, which says it is in the UTC-5 time zone.

What is CDT? 

Central daylight time is about five hours behind the coordinated universal time. This means that to find the central daylight time of a particular zone, you have to subtract five hours from the coordinated universal time of that region.

The zone runs through the middle part of Canada, the United States, and most parts of Mexico. It also encompasses the central part of America, the Caribbean Island, and the eastern part of the Pacific Ocean.

What is PDT? 

PDT is the daylight-saving time called summertime the PST, which is pacific standard time. The difference between the several time zones to each other is always specified in relation and comparison to the universal time coordinated, the UTC, which is the time on the prime meridian that is the zero on longitude.  

Let’s talk of an example. New York is currently on the 74th degree on the west’s longitude, which says it is in the UTC-5 time zone. And in the summer days, the clock is switched ahead of the time zone by one hour. The pacific daylight times apply to two countries and are consistent with the UTC-7.

Main Differences Between CDT and PDT 

1. The difference between the several time zones to each other is always specified in relation and comparison to the universal time coordination that is the UTC.
2. CDT is applied in the central part of America, but PDT is applied in the northern part of America.
