I wish I could upvote this twice because it's the best explanation WHY we want DST. Late daylight summertime is very useful for all kind of outdoor activities. The late daylight is mostly applicable for those of us at northern latitude, and exactly we are these who can enjoy most outdoor activities only in the hot part of the year. So I guess DST makes much lesser sense to those living near the Equator.

Most tropical countries don't have DST, because there'd be no point in it when there are no seasons, but some use a different time zone, which can have the effect of "year-round DST".
