Hes made a list, hes checked it twice, and now Santa Claus is working his way around the world on his busiest day of the year. And with Amazon workers on strike, and American Airline flights being briefly grounded on Christmas Eve, holiday revelers might just need the extra help to get their Christmas gifts on time. Each year, NORAD, the North American Aerospace Defense Command, provides real-time tracking of Santa and his reindeer starting at 6 a.m. ET on Christmas Eve, when Saint Nick leaves the North Pole and starts his journey on sleigh to deliver hundreds of millions of gifts to children. (As of this writing, Santa was in the Indian Ocean making his way west.)To see where Father Christmas is at any given moment, simply go to NORADs website and click on View Santas route on a 2D map, to look for Santas big red hat icon. Other cool features are a running tally of all gifts hes delivered (2,681,010,867 at this writing), in addition to camera icons along his route that link to a Wikipedia summary of the locale.A brief history of high-tech Santa trackingIn case youre wondering: The tradition dates back to 1955 when a young child mistakenly called a Colorado military command center asking to speak toSanta.According to NORAD, the commander on duty that nightassured the child he was, indeed, Santa. And after more incoming calls, Air Force Colonel Harry Shoup assigned a duty officer to continue monitoring the phones,a tradition that has continued ever since.Wait, can kids still call and speak to Santa?Yes! Today, inquisitive kids and their parents can dial 1-877-HI-NORAD (1-877-446-6723) to speak to Santa. Each year, volunteerstypically received more than 130,000 calls.
