Most of the US, Canada and Mexico's northern border cities will start Daylight Saving Time at 2 am local time on March 14, 2021. The clocks will "spring forward" an hour to daylight time, so that evenings have more daylight and mornings have less. The most of Europe will start DST on the last Sunday in March.
We have placed a detailed description of this event on this page: Daylight Saving Time 2020. For further information please stop by there!
