Daylight Saving Time Comes to an End at 2 a.m. on November 1st

Posted on November 1, 2015

Clocks will need to be rolled back one hour at 2 a.m. today, November 1st. This is because this is when Daylight Saving Time (DST) comes to an end. It always ends on the first Sunday of November, which this year happens to be November 1st.

The National Institute of Standards and Technology (NIST) provides a good explanation of DST here. The DST part of the year begins the second Sunday in March at 2 a.m. We have been in DST since then and now we come out of DST and back into standard time.

There are some parts of the U.S. that not observe DST, such as most of Arizona and Hawaii. The NIST site also lists U.S. territories that do not follow DST. Here is a handy video from National Geographic called Daylight Saving Time 101. Take a look:
