Sorry for the typo in the previous comment. "Celebrate", not "celebrated". Slip of the key...

Badly researched in several places. The Dutch and Belgian inaccuracies concerning Sinterklass and Christmas have already been noted. I'll speak on behalf of central European inaccuracies : Austrians, Czechs, Slovaks and Hungarians celebrated both Saint Nicholas (on the 6th of December) and Christmas on the 24th-26th. Gifts are given during both holidays, though the bigger and main ones are at Christmas Eve, on the 24th. Saint Nicholas (St. Nick, Nikolaus, Mikuláš, Mikulás) brings gifts on the 6th December, while the Baby Jesus (Christ Child) brings gifts on Christmas Eve. This counts for all four of these countries, so the erroneous entry for Slovakia just comes across as bizarre and lazily researched. I urge the author of the image to update it and fix the issues. If he/she wants the image to be really informative, then the information contained within should be accurate. Thanks for hearing me out and a Merry Christmas (or whatever holiday you might be celebrating) to all ! :-)
