Common Time Zone Questions

When does Daylight Saving Time start and end?
Daylight Saving Time starts the second Sunday in March (spring forward) and ends the first Sunday in November (fall back). Remember: Arizona and Hawaii stay on standard time all year.
How many time zones does the U.S. have?
Six main time zones cover the United States: Eastern, Central, Mountain, Pacific (continental US), plus Alaska and Hawaii-Aleutian. US territories like Puerto Rico and Guam add more zones.
What's the difference between EST and EDT?
"ST" means Standard Time (winter), "DT" means Daylight Time (summer). EST is UTC-5, EDT is UTC-4. Each zone shifts one hour forward during DST, except Arizona and Hawaii.
Why doesn't Arizona observe DST?
Arizona chose to skip DST in 1968 to avoid extra evening heat during scorching summers. Interestingly, the Navajo Nation within Arizona still follows DST, creating a time zone puzzle.
What time is it on the East Coast vs West Coast?
There's a consistent 3-hour gap between coasts. Noon in NYC equals 9 AM in LA. This difference stays constant whether during standard time or daylight saving time.
Which states span multiple time zones?
Thirteen states cross time zone boundaries, including Florida, Texas, Tennessee, and Idaho. This can make scheduling tricky - always check which part of the state you're dealing with!
