I recently purchased an internet add-on through the Digi app. It says 12am - 6am. AFAIK, 12am is 12 noon and not 12 midnight. But then again, others may not understand it that way. I suggest that Digi clarifies that it is actually 12 midnight and not 12 noon.
12 a.m. refers to 12 midnight, the start of the specified day (00:00), carolyncory.
Have a pleasant day!
