When does it start to get dark in spring?

At six or seven o'clock, it gets dark all the year round. The four seasons are different, and the dark time is different. The days get shorter in spring and winter. Under normal circumstances, it will get dark at five or six every day. In summer and autumn, the weather is hot and the days will get longer. It will get dark around six or seven. If it rains, it may get dark ahead of time, but the difference will not be too long, about an hour.
