Booklist Review

Gr. 3^-5. First, author Maestro puts things into perspective. Although it seems like a big deal to us, the beginning of the next millennium is insignificant compared with the overall age of the universe: "Our universe is probably at least twelve billion years old. A billion years is made up of one million millennia." This clear explanation typifies Maestro's ability to sort out complicated facts and make them understandable. Although the change to the next millennium is a selling point, most of the book is about the ways humans mark time, covering the Julian and Gregorian calendars, and touching on the Jewish, Muslim, and traditional Chinese calendars as well. The information will satisfy most report requests, as well as reference questions, such as how the days of the week got their names. Giulio Maestro's bright pictures are a mix of colored pencil, watercolor, and other media, and virtually all of them add more information with diagrams and labels. Most libraries will want at least one copy. --Susan Dove Lempke

School Library Journal Review

Gr 2-5-Maestro begins with a discussion of calendars: how, when, and where they originated; the different types; and how various countries, rulers, and religions influenced timekeeping. She then discusses the passage of time marked by sundials and hourglasses, provides a general description of early clocks and watches, and brings the subject up to the present with a mention of the atomic clock. The final pages address the question of when the millennium actually begins. Maestro's writing displays its usual objectiveness and clarity. Detailed illustrations of artifacts, including the earliest-known calendars carved into bone, and colorful background scenes done in pencil, colored pencils, ink, and watercolors enhance the descriptions and add immensely to the overall success of the book. The glossary and endnotes supply additional facts about expressions, the names of the days of the week, and computers and the year 2000. The only thing lacking from this otherwise all-inclusive book is a list for further reading. Be sure to purchase more than one copy of this timely volume.-Kit Vaughan, J. B.

The Story of Clocks and Calendars Marking a Millennium For as long as anyone can remember, people have thought of the year 2000 as "the future" -- a time way ahead of us, when somehow things would be different and new. Stories set in the year 2000 and beyond have always been part of science fiction -- something from the imagination. Now that future is about to become reality. Although January 1, 2001, will officially begin the new millennium, the festivities will start a year before that date, when New Year's Eve is celebrated, December 31, 1999. People all over the world are looking forward to this rare event with great excitement. But what makes this date and time so special? What is all the fuss about? The year 2000 is both a great milestone, a time to mark two thousand years of human achievement, and a historic beginning, the entry into anew thousand-year period - a new millennium. It is also an important time for people of the Christian religion, who will be celebrating the two-thousand-year anniversary of the birth of Jesus Christ. People mark the passing of celebrate birthdays by counting the years.Each year we celebrate birthdays and anniversaries, counting the years since the people we know were born or married.Even one year can seem like a very long time, so the passing of one hundred years - a century - has always been given special notice.A thousand years is ten times as long as a century, so a new millennium is a truly awesome event. But even though the year 2000 seems very important to us, it is really only a tiny part of the long story of time, where a year is shorter than the blink of an eye.A millennium is a very long time in human history but only a short time in the history of our planet and universe. Our universe is probably at least twelve billion years old, and our earth is about four and a half billion years old. It is difficult for us to imagine such long periods of time. A billion is a really large number - more than a hundred, more than a thousand, more than a million. A billion years is made up of one million millennia. So our earth has lived through millions of millennia, and scientists now think that Homo sapiens - humans like us - could possibly have lived on earth for as many as two hundred millennia. Why, then, is everyone making such a fuss about the year 2000? And how can this be only the year 2000 when our earth is so much older and people have been around for such a long time? The answer is that it is only the year 2000 on the Gregorian calendar - the calendar most people use. There are many other calendars. The year 2000 will begin in the year 5760 on the Hebrew calendar and in 1420 on the Muslim calendar. It will be 4698 on the Chinese calendar. So what year is it really? There is no one answer. It depends on what calendar you use and how long ago your calendar began counting the years. But the Gregorian calendar is the standard calendar used around the world, and for everyone who uses that calendar, it will be the year 2000. A calendar is one way to keep track of time. We look at it every day to see what day, month, or year it is. A clock also helps us to measure time. We look at it to see if it's time for school or soccer practice or bed. Everyone needs to know what time it is, so clocks and calendars are important in our lives. The Story of Clocks and Calendars Marking a Millennium . Copyright © by Betsy Maestro.
