Has Ramadan ever fallen on Christmas day?

the Islamic calendar is a lunar calendar of of approx 355 days. Ramadan is an entire month of 28 to 30 days, depending when the new moon is sighted.

Since we in the West follow a solar calendar of 365 .25 days, it stands to reason, the Islamic calendar month of Ramadan would fall ten days earlier every year. So it takes approx 30 years to make its way completely around the calendar and for about 3 years every 30, Christmas Day conincides with the month of Ramadan.
