As England spans several latitudes, the exact timing of twilight will vary from place to place. Additionally, the seasons affect the day's length and, consequently, the timing of twilight. Twilight occurs earlier in the day during winter and later in the day during summer.
To determine the specific times of twilight for a particular location and date, it's best to use an online twilight calculator or refer to an astronomical almanac for precise information. These resources take into account your location, the day of the year, and the type of twilight you're interested in.
