US Daylight Saving Dates Calculator: This free tool instantly shows you the exact start and end dates of Daylight Saving Time for any US year, following the current federal rules established in 2005. DST begins on the second Sunday of March and ends on the first Sunday of November, with clocks shifting forward at 2:00 AM and back at 2:00 AM respectively.
Current Federal Rules: Since 2007, the United States has observed DST from the second Sunday in March to the first Sunday in November. This was set by the Energy Policy Act of 2005 and applies to most states except Arizona (except the Navajo Nation) and Hawaii. The tool works for any year from 2007 onward.
How It Works: Enter a year and the tool calculates the exact dates. DST always starts at 2:00 AM local time on the second Sunday of March, when clocks spring forward to 3:00 AM. It ends at 2:00 AM on the first Sunday of November, when clocks fall back to 1:00 AM. The tool also tells you how many days DST is in effect.
Practical Applications: Airlines, broadcasters, and event planners in cities like Austin, Chicago, and New York all need to account for DST transitions. Scheduling software, payroll systems, and meeting invites must handle the 60-minute gap in spring and the repeated hour in fall. Missing a DST change can cause missed flights, double-booked meetings, or payroll errors.
Privacy and Speed: All calculations run instantly in your browser. No data is sent anywhere, and the tool is completely free to use with no signup required ever. You can look up DST dates for multiple years in seconds.
State Exceptions: Arizona and Hawaii do not observe DST. The Navajo Nation in Arizona does observe it. If you are scheduling across state lines, always verify which rule applies to your specific location.
