When does the sun rise now? I want to set an alarm clock to watch the sunrise.

When the sun rises varies from place to place. With my shallow knowledge, I can write a theoretical deduction of minute calculation accuracy. However, the calculation is necessarily lengthy and extremely troublesome.

Give the landlord several ways to find the answer directly. The first way is to go to the interface of China Weather Network, where there will be sunrise and sunset. For example, the sunrise in Shanghai today is 5:2 1.

The second is to simulate with astronomical software. Personal habit is to observe the moment when the sun cuts the horizon with an astrolabe, which can be accurate to the second.

PS suggested that the landlord pick a cloudy day and enjoy it half an hour in advance. The most beautiful sunrise is the morning glow, and the bottom of the cloud slowly turns red and purple. This is my favorite moment of glory.
