Science and History of Santa Claus:

How long does Santa have on Christmas Eve?
If Santa were to start delivering gifts at 10 pm on Christmas Eve and finish at 6 am on Christmas morning, that would give him only 8 hours to deliver presents. Or would it? Santa must circle the globe. How would that affect how many hours he has for his work?

International Date Line
The date in the Eastern hemisphere (to the left of the Int’l Date Line) is always one day ahead of Hawaii. So, Santa would gain 24 hours if he traveled west, around the globe.

In that time, how many houses does Santa visit?
There are about 378 million children whose families celebrate Christmas At an average of 3.5 children per household, that would mean that Santa would visit 108 million homes To reach all those homes, Santa’s flying reindeer would have to travel at many times the speed of sound. Source:

English: Thomas Nast's most famous drawing, "Merry Old Santa Claus," from Harper's Weekly (January 1, 1881, p.8-9).Thomas Nast immortalized Santa Claus' current look with an initial illustration in an 1863 issue of Harper's Weekly, as part of a large illustration titled "A Christmas Furlough" in which Nast set aside his regular news and political coverage to do a Santa Claus drawing. The popularity of that image prompted him to create another illustration in 1881.

Are Santa’s reindeer girls?
Male and female reindeer both grow antlers. But the antlers of older males fall off in December. So, since Santa’s reindeer have antlers on Christmas, Dasher and Dancer are most likely girls.
