A term that, while an attempt to be inclusive of various winter holidays and "festivals of light", also displays ignorance that Ramadan has no connection with the seasons of the solar year. Ramadan (a month of major religious observances within the Islamic lunar calendar) moves backwards through the solar calendar about eleven days every year.
In some years Ramadan gains visibility as it is coincidentally observed near the winter "holiday season", but it actually keeps cycling through the seasons.
In 2010 Ramadan spanned parts of August and September.
In 2011 Ramadan will fall approximately between August 1 and August 29 or 30.
This demonstrates that "Christmahannukwanzadan" illogically groups Ramadan with winter holidays.
