I have a datalogger which records the amount of time the sensor is below
freezing, this is quoted in either hours / minutes or Days / Hours /
Minutes. I would be interested to know how other people calculate this data.
The figures I have for February for my station are

Hours Minutes
08 18 01-03 Feb
35 43 03-10th
63 06 10-17th
37 12 17-24th
11 08 24-29th

Which gives me a total of 155hrs 27min.

My datalogger doesn't automatically calculate this, but Excel crunches
the numbers easily.

I recorded 113hrs 25min below freezing last month.
