Spring Forward: The Annual Madness of Daylight Saving Time is a history of the most confusing American tradition and its mind-bending side effects. It is loaded with facts but is a surprisingly light read, which makes it both informative and fun.
My mental concepts of time and the calendar have always included Daylight Saving Time, as it was entrenched here in the northeast long before I arrived. Having its existence highlighted and its ostensible goals explained was very thought provoking though. It raised a number of questions for me, ranging from the reasonable extents of government power and the influence of business on society to the inevitable conflicts between different lifestyles and the amazing power of myth. (Hint: Daylight Saving Time is not for farmers.) And it even furthered my belief that Ben Franklin was the devil.
Finding all that in 150 pages is pretty impressive, if you ask me.
Bottom line: 4 out of 5 stars. The only reason not to give it a full 5 stars is that I doubt it'll change anyone's life. Nonetheless I found this to be an enjoyable read and I'd recommend it heartily.
