We, sundial experts are not very pleased with DST. This dissatisfaction is due not so much to DST but to the organization of our daily routine. We sleep from 23.00 pm to 7.00 am. Our active day is from 7.00 am to 23.00 pm. The middle of the active day is at 15.00 pm. If winter time is on use the real noon in my location is at average 12.40 pm When DST is on use the real noon is at 13.40 pm There should be an extra hour added to DST ! Then the real noon almost coincides with the middle of our active day. We then use the maximum sunlight during our activities.
