Wow, the final score in De Bilt (near Utrecht, and where the Dutch met office is based) using the rating system designed to fit their winter weather patterns is 0.0! First winter ever in more than 100 years not to score any points at all. I'd suspect most places in Britain apart from some Scottish valleys would be on 0.0 too, but that wouldn't be quite as unique.

Maybe the hellmann score is unknown in Finland or other countries.

I'm confused. Does this measure the amount of frosts or days with a mean below freezing. Would a day with a high of 5 C and low of -2C count?

No, because that doesn't average below freezing. A high of 2 and a low of -5 however would add 1.5 points to the total.

Ah, I read a local article about this. Usually winters here get 600-800 points, this one only got something over 200. Goes to show how ridiculously mild it's been for months and months.

0 since we are talking about daily means.
If we were discussing the sum of Tmins below 0ºC it would be 77.7
