I typed "when is daylight savings time" into google and found this:

Daylight Saving Time begins for most of the United
States at 2 a.m. on the first Sunday of April.
Time reverts to standard time at 2 a.m. on the last
Sunday of October. In the European Union, it
starts at 1 am the last Sunday in March, and ends
the last Sunday in October.
Daylight Saving Time, for the U.S. and its
territories, is NOT observed in Hawaii, American
Samoa, Guam, Puerto Rico, the Virgin Islands, the
Eastern Time Zone portion of the State of Indiana,
and the state of Arizona (not the Navajo Indian
Reservation, which does observe). Navajo Nation
participates in the Daylight Saving Time policy,
due to its large size and location in three states.
