christmas is a standard holiday for thousands of christians all around the world, but there are those who choose to follow a different, religion...choosing different days and ways to celebrate holidays, the trick is when desiring to give one a gift, but not sure when because they do not, celebrate the holiday i'm traditionally rooted in.

what would be proper gift sending ettiquette, give them a gift on their holiday, from your holiday, or just a general happy whatever holiday sort of sentiment?
