Had the idea of a government plan to shift the clocks back and forth twice and year been proposed today I am reasonably certain that I would have been against it. I probably would have argued that it would be chaotic, inefficient and unnecessary (private firms could agree with their employees to change working hours at any time, right?). Central planning of time! Washington bureaucracy messing with the clocks! Get your government hands off my time!
And yet, it works and I like it. It is good to be reminded of this twice a year.
