Daylight Saving Time arrives Sunday (March 13), which means spring isn’t far behind.

How far behind depends on the source you consult, and where you are.

But first, remember to set your clocks ahead one hour (spring forward!) Saturday night. Daylight Saving Time officially begins at 2 a.m. Sunday. Your digital devices will probably take care of that for you automatically.

As for spring — according to the Old Farmers Almanac, astronomically speaking the vernal equinox (12 hours of daylight, 12 hours of darkness) arrives at 9:30 p.m. on March 19 in the Pacific Time Zone. But that is 12:30 a.m. in the Eastern Time Zone, so spring there begins on March 20.

According to the Old Farmers Almanac, this will be “the earliest spring of our lives” — thanks in part to 2016 being a leap year, in which February has 29 days.

Standard time returns on Nov. 6.
