Between 5:30, which was my get-up time when I w@rked, and around 6:45. I don't like to doze much beyond 7 unless we had a late night. If it's one of those nights when I wake up before 2:30-ish and have trouble dozing off again, I'll take the 1 mg sub-lingual melatonin I leave on the nightstand for those restless wee hours.
