Meter reading puzzle

When I read the elec. meter, one number is labeled ‘Rate 4’ and the other ‘Rate 1’. which is the day and which the night?

Hi @brownliza2 tricky one, the best way I’ve found is to look at the meter twice during the day (or the night, but that might be a bit less convenient, say half an hour or so apart, and see which has moved. Otherwise you could take a look at a recent bill, and see what the readings are on the day and on the night bits of the bill, but that might be a bit more fiddly.
