I'm talking about the modern rationale, not the historical one.

Also, no, it wasn't to conserve fuel for the winter. It was to conserve fuel during the summer so it could be used in the war, also during the summer.

But it's not like we forgot to change back. It's that we decided we really liked the longer usable daylight in the summer. There have been tons of adjustments to DST since WWII, reflecting the fact that we like it in the summer, and have variously adjusted which months it covers.

The point is, it is literally described as saving daylight, which is what I explained. "Saving" it in the morning to use in the evening. The "saving" in the name always referred to daylight, not to fuel.
