Hi @whyaskwhy,

According this article almost all the countries except five were colonized by the European countries.

If you remember this video that gives proof of why Christianity was the real driving force behind European colonization you will see the real reason why Christmas is a public holiday in many countries.

If you understand the content of the above video you will know that it is nothing to be proud of.

In fact it is a sad reminder of how surreptitious and conniving the church is and how naive and ignorant many people are.
