Daylight Savings Daylight saving is a period from late spring to early fall when many countries set their clocks
ahead of normal local time by one hour to give more daytime light in the evening.

Daylight Saving Time starts in most parts of the United States on the second Sunday of
March. Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local
time. So in the United States you would select Se c o nd, Sunda y, Ma rc h and select 2 in the a t
field.
Daylight Saving Time starts in the European Union on the last Sunday of March. All of the
time zones in the European Union start using Daylight Saving Time at the same moment (1
A.M. GMT or UTC). So in the European Union you would select La st, Sunda y, Ma rc h. The time
you select in the a t field depends on your time zone. In Germany for instance, you would
select 2 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).
