Soon we will be losing an hour of daylight. What is the purpose of daylight savings time if you only lose it?

We have the same amount of daylight. It just comes in the morning instead of at night. If you got up before noon, you would know that.

So night crawlers like me have our turn to crawl around an extra hour.

I can't see why we can't all stick to standard time for our respective longitude time-zones, year-round. We don't "save" daylight; we don't alter the hours of light and dark; we simply and artificially fit our lives to when we think the sun should rise and set. 

Daylight Saving Time. Singular, not plural. Many, MANY people incorrectly refer to it as "savings".
