1, the sunrise time of the summer solstice is 5 am 16: 48. Sunset time is 6: 43: 12 seconds.

2. Given the latitude a of the point where the sun shines directly on the earth, find the sunrise time of any point on the earth (known latitude b) and get a formula: t = 12 * arccos (TGA * TGB)/π (applicable to the northern hemisphere).

3. According to the calculation, summer solstice: the direct point of the sun is also on the tropic of cancer, a = b = 23 26', t = 5.28 is brought into the formula, and the sunrise time is 5: 00 am16: 48. Sunrise time and sunset time are symmetrical at noon 12, so the sunset time from summer to morning is 6: 43 pm12 seconds.
