Hm. A quick search suggests that 70 countries out of 195 have daylight savings time, with a fair number of those considering abolishing it. Most of those are in Europe. 73 countries have abolished DST, and 106 have never had it in the first place.

Not 100% sure on those stats. They come from AI, and I only spot-checked it. But yeah. Most northern climate countries do currently have DST.
