Good to know

About EST and MST

  • Eastern Time is used in New York, Florida, Georgia, Ontario, and Quebec. Eastern Time switches to EDT for daylight saving time from the second Sunday in March to the first Sunday in November.
  • Mountain Time is used in Colorado, Utah, New Mexico, Montana, and Alberta (most of Arizona stays on MST all year). Mountain Time switches to MDT for daylight saving time from the second Sunday in March to the first Sunday in November.
  • Both zones change their clocks on the same dates, so the difference stays the same all year.
  • People often say EST all year, but strictly EST is the winter time and EDT is the summer time. This page covers both.
