What is Daylight Saving Time (DST) / US IT Recruitment:

In the United States, Daylight Saving Time (DST) begins on the second Sunday in March and ends on the first Sunday in November. During DST, clocks are turned forward by one hour, which means that there is more daylight in the evenings and less in the mornings. This change is intended to make better use of natural daylight and to conserve energy.

Summer daylight saving time in America always starts on the 2nd Sunday in the month of March and ends on the 1st Sunday in the month of November. This is being followed since the year 2007.

However, it’s important to note that not all states in the US observe DST. Hawaii and most of Arizona do not participate in DST, while some territories like Puerto Rico and the Virgin Islands also do not observe it.

So, there is always a discussion that eliminates DST altogether in a few states.


DST Difference:

To understand DST in a better way, let me give you an example below-

EST (Usual Time) EST (DST Time)
9.00 am 8.00 am
CST (Usual Time) CST (DST Time)
8.00 am 7.00 am
MST (Usual Time) MST (DST Time)
7.00 am 6.00 am
PST (Usual Time) PST (DST Time)
6.00 am 5.00 am
