5.0 von 5 Sternen one of the best books I read in 1999

A history of the Egyptian, Mayan, Chinese, Jewish, French Republican, Roman, prehistoric and present-day Gregorian calendars is provided.

3.0 von 5 Sternen Interesting but flawed
Very interesting history of the major calendar systems used around the world, both in the present day and in the past. It also gets into the mathematics of how to convert between calendar systems, including algorithms suitable for computer programming.

Very interesting history of the major calendar systems used around the world, both in the present day and in the past. It also gets into the mathematics of how to convert between calendar systems, including algorithms suitable for computer programming. Unfortunately, there are numerous typographical errors in the narrative and in the algorithms! The word "temperature" where the author clearly meant "temperate", substitution of "*" for "-" in a formula, etc. So far, I have been able to correct the formula for computing the day of the week and the formula for computing the date of Easter. I'm not looking forward to tackling the other algorithms. Did anyone proofread this before it was printed? Maybe the publisher could put up an errata sheet on their web site.
Good for the history, but be prepared to do some algebra if you want to use the algorithms.
