Why Doesn't My Older Clock Change for DST?

Follow

If your older clock does not change for DST:

Starting in 2007, the United States and Canada began Daylight Saving Time (DST) on the second Sunday of March and end on the first Sunday of November. From 1987 to 2006, DST began on the first Sunday in April and ended on the last Sunday of October.

  1. If your clock was manufactured before 2007, it will have to be manually adjusted.
