CDT stands for central daylight time, which is used by most of the zones basically during summertime which is approximately five hours behind the UTC. It is used by three countries in the northern part of America.
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. It is only used by two countries which are in the northern part of America only.
CDT vs PDT
The main difference between CDT and PDT is that CDT is five hours before the coordinated universal time, but PDT is seven hours before the coordinated universal time. Both the time zones- central and pacific are used by different countries and during the summertime basically. CDT is applied and is used in three countries- Canada, United Staes, and Mexico but the PDT is used and applied only in two countries- Canada and United States.
The central daylight time is used by most of the zones around the globe during the summertime. The largest city that falls under the central time zone is Mexico City. Mexico is the largest metropolitan city in the zone and in North America. It starts on Sunday of March, and It ends on the first Sunday of November.
The pacific daylight time is the time zone that is used in North America and is about seven hours behind the coordinated universal time. For example- New York is currently on the 74th degree on the longitude on the west, which says that 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.
Comparison Table Between CDT and PDT
| Parameters of Comparison | CDT | PDT |
| Abbreviation | CDT stands for Central daylight time | PDT stands for Pacific daylight time |
| Countries | It is applied in Canada, United States, Mexico. | It is applied in Canada, United States. |
| UTC | CDT is five hours before UTC. | PDT is seven hours before UTC. |
| Start date | It starts on Sunday of March. | It started on March 14. |
| End date | It ends on the first Sunday of November. | It ends on November 7, according to United States’ time. |
| Meaning | CDT stands for central daylight time, which is used by most of the zones basically 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. |
What is CDT?
The central daylight time is about five hours behind the coordinated universal time. This basically means that in order to find the central daylight time of a particular zone, you have to subtract five hours from the coordinated universal time of that region. Currently, the territories that are observing the time zone are basically in the middle part of North America and in the central part of North America.
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. The whole of central America and Canada actually refers to this time zone as the central daylight-saving time zone (CDST).
What is PDT?
PDT is the daylight-saving time called summertime of 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 that is 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 longitude on the west, which says that 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 generally apply to two countries and are consistent with the UTC-7. That means the PDT is seven hours before the universal time coordinated.
Main Differences Between CDT and PDT
- The main difference between CDT and PDT is that CDT is five hours before the universal time coordinated and the PDT is seven hours before the universal time coordinated.
- CDT is applied and is used in three countries- Canada, United Staes, and Mexico but the PDT is used and applied only in two countries- Canada and United States.
- The CDT starts on the Sunday of March every year, but the PDT starts on March 14 every year.
- The CDT ends on the first Sunday of November every year, but PDT ends on November 7.
- CDT stands for central daylight time, but PDT stands for pacific daylight time and is used basically in the summertime.
- The difference between the several time zones to each other is always specified in relation and comparison to the universal time coordinated that is the UTC.
- CDT is basically applied in the central part of America, but PDT is applied in the northern part of America.
Conclusion
From the discussion so far, it is to be concluded that both the time zones- central and pacific are used by different countries and during the summertime basically.
CDT stands for central daylight time, which is used by most of the zones basically 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. Currently, the territories that are observing the time zone are basically in the middle part of North America and in the central part of North America. The whole of central America and Canada actually refer to this time zone as the central daylight-saving time zone (CDT).
PDT is the daylight-saving time called summertime of 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 that is the UTC.
