2.3. Impact of Daylight Saving Time (DST) on MT
Daylight Saving Time (DST) is observed in most areas of the Mountain Time Zone from the second Sunday in March to the first Sunday in November. During DST, clocks are advanced by one hour, shifting the time to UTC-6, known as Mountain Daylight Time (MDT). However, it’s important to note that Arizona does not observe DST, except for the Navajo Nation, which follows DST. This can create further complexities when coordinating schedules between different regions within the Mountain Time Zone.
3. The Time Difference: Mountain Time vs. Eastern Time
The time difference between Mountain Time (MT) and Eastern Time (ET) is two hours. Eastern Time is always two hours ahead of Mountain Time. For example, when it is 2:00 PM ET, it is 12:00 PM MT.
3.1. Calculating the Time Difference
To calculate the time difference between ET and MT, subtract two hours from the Eastern Time to find the corresponding Mountain Time. Conversely, add two hours to the Mountain Time to find the corresponding Eastern Time.
3.2. Practical Examples of Time Conversion
Here are a few practical examples of time conversion between ET and MT:
- 3:00 PM ET is 1:00 PM MT
- 8:00 AM ET is 6:00 AM MT
