When does winter end 2013?

Answer 1

Different people and places have different definitions for the beginning and end of each season. I follow the rule by which the seasons begin at the times of the solstices and equinoxes.

In the northern hemisphere, winter 2013 ends on March 20 at 11:01 AM UTC. Therefore, the last full day of winter is March 20 in the Line Islands of Kiribati that are north of the equator and March 19 throughout the populated lands of the rest of the northern hemisphere.

In the Southern Hemisphere, winter 2013 ends on September 22 at 8:43 PM UTC. Therefore, the last full day of winter is September 22 in Southern Hemisphere time zones east of and including UTC+4 and September 21 in southern hemisphere time zones west of and including UTC+3.
