On Sunday night and early Monday morning, Santa Claus will be delivering presents around the globe to good little boys and girls.

However, who is this guy in the red suit who travels with a big sack? Here's what you need to know.

Is Santa real?

According to the website of the North American Aerospace Defense Command, which tracks Santa's trip every year, mountains of historical data and NORAD tracking information lead us to believe that Santa Claus is alive and well in the hearts of people throughout the world.

What should I leave out for Santa?

Santa loves all cookies. He likes a glass of milk or egg nog. Also, remember to leave a few carrots out for the reindeer.

How many reindeer does Santa have?

Santa has either eight or nine reindeer. The reindeer, named in Clement Clarke Moore's poem "A Visit from St. Nicholas," are Dasher, Dancer Prancer, Vixen, Comet, Cupid, Dunder and Blitzen.

The ninth reindeer is Rudolph the Red-Nosed Reindeer. According to the 1939 storybook and Gene Autry's 1949 Christmas song, Rudolph leads Santa's sleigh so he can navigate through clouds and fog.

How old is Santa?

Santa Claus, whose birthday is March 15, is 1,753 years old. Santa, also known as Saint Nicholas, was born in 280 AD in what is now Turkey.

What is Santa’s phone number?

Do you want to give Santa a call and let him know what you want for Christmas? Easy enough, just dial (605) 313-0691.

Because Santa is busy making preparations for his trip around the world, don't be surprised if the call goes to voicemail. If you call using a cellphone, the hotline will record your child's message and send it back via text.

How can Santa travel the world in 24 hours?

Leave it to the folks at NORAD to figure out Santa's travel plans.

"NORAD intelligence reports indicate that Santa does not experience time the way we do. His trip seems to take 24 hours to us, but to Santa, it might last days, weeks, or even months ... so the only logical conclusion is that Santa somehow functions within his own time-space continuum," according to NORAD's website.
