Frequently Asked Questions
What is the time difference between MST and CEST?
During standard time, Central European Summer Time is 9 hours ahead of Mountain Standard Time.
Does Arizona observe Daylight Saving Time?
Most of Arizona — including Phoenix, Tucson, and the state government — does not observe Daylight Saving Time, remaining on MST (UTC-7) year-round under a state law in effect since 1968. The significant exception is the Navajo Nation, which spans parts of northeastern Arizona, Utah, and New Mexico and does observe DST, creating one of the most complex intrastate time zone situations in the United States.
What is the difference between MST and MDT?
MST (Mountain Standard Time) is the winter offset at UTC-7:00, observed from the first Sunday in November through the second Sunday in March. MDT (Mountain Daylight Time) is the summer offset at UTC-6:00, applied when most Mountain Time regions advance their clocks by one hour during Daylight Saving Time.
When does CEST start and end?
CEST begins on the last Sunday in March at 02:00 local CET time, when clocks spring forward one hour from CET (UTC+1) to CEST (UTC+2). It ends on the last Sunday in October at 03:00 local CEST time, when clocks fall back to CET. In 2026, CEST runs from March 29 through October 25, covering approximately seven months of the year across all EU member states that observe this schedule.
Is CEST the same as CET?
CEST and CET are two phases of the same Central European Time zone. CET (Central European Time) is the winter offset at UTC+1, observed from late October through late March. CEST (Central European Summer Time) is the summer offset at UTC+2, active during the EU Daylight Saving Time period — meaning Berlin, Paris, and Rome run one hour ahead of their winter clock for roughly seven months each year.
