TLDRAt 10 o’clock p.m. on the 21st of June, the longest day of the northern hemisphere, the aspect of the sky is that shown in Chart II, accompanying this chapter. The same chart will answer for 11 p.m. on the 5th or 6th of June; 9 p.m. on the 7th of July, and 8 p.m. on the 22d or 23d of July. In fact, for any of the hours mentioned the date may be shifted several days forward or backward without seriously affecting the comparison of the chart with the sky, and the same may be said of each of the other circular charts. The stars simply rise about four minutes earlier each evening, and four minutes of time correspond to one degree of space measured on the face of the sky. So the whole sky shifts about one degree westward every twenty-four hours.via the TL;DR App
