It's an institution in this country like a tin of USA Biscuits or the Toy Show. We are, of course, talking about Christmas FM.
Our favourite radio station - sorry, everyone - is back on the air officially from today and will be spreading Christmas cheer across the nation until some time in early January.
This year, ChristmasFM is partnering with Age Action Ireland and all texts to the station will go directly to the charity.
So, depending on where you are, the radio frequency will change. Here's how to tune in.
Dublin City and County - 94.3FM
Dublin Commuter Area, Greater Kildare - 88.1FM
