The Big Con
Daylight Saving Time is a massive con anyway. It doesn't really save anything. The mass confusion it causes almost certainly outweighs any benefit it may once have had.
In Summer, we get more daylight. That is a fact. It's evenly split about a point called "local solar midday". Along the Greenwich Meridian, solar midday always occurs around 12:00 UTC; it shifts by four minutes for each degree of longitude. At mid-spring, 21 March, and mid-autumn, 21 September, we get exactly 12 hours of daylight from 06:00 UTC to 18:00 UTC. At midwinter, 21 December, the UK gets only 8 hours of daylight from 08:00 until 16:00 UTC; but at midsummer, we receive 16 hours, from 04:00 until 20:00 UTC.
It so happens that the "standard" working day of 09:00 to 17:00 is centred an hour *after* midday. This gives time to get washed and dressed for work by daylight, even in the very depths of Winter. However, it also means that in the height of Summer, some of the daylight hours occur while people are still sleeping: getting up sooner would give a longer continuous period of daylight.
What would surely have been logical, would have been to alter the working day. Have businesses work from 09:00 to 17:00 in the Winter and from 08:00 to 16:00 or 07:00 to 15:00 in the Summer. And twice a year, for a few weeks, there would even be just a bit less traffic on the roads due to different businesses switching on different dates.
Instead, we forced everyone to pretend it was 13:00 when it was really midday -- and we continue to do so, despite the fact that most modern workplaces are not dependent upon natural daylight.
