On October 25, the time of sunset in Kursk and St. Petersburg coincided – 17 hours 24 minutes, but on the same day in Kursk

On October 25, the time of sunset in Kursk and St. Petersburg coincided – 17 hours 24 minutes, but on the same day in Kursk the sunrise was at 7 hours 18 minutes, and in St. Petersburg at 8 hours 02 minutes. These cities are in the same time zone, why was the length of the day in Kursk longer? Why did the moments of sunset coincide, but the moments of sunrise are different?

1) (it is indicated why the day was longer in Kursk – the influence of latitude)
The cities are in the same time zone, but at different latitudes. Since St. Petersburg is located to the north, and the autumn equinox has passed, the length of the day in Kursk is longer.
2) (influence of longitude)
Kursk is located east of St. Petersburg, so on the days of the equinox both sunrise and sunset occur earlier in Kursk, although the length of the day is the same.
3) (the correct conclusion is made)
Thus, due to the fact that the duration of the day in St. Petersburg in winter time is shorter than in Kursk, in the northern capital, the time of entry shifts downward (earlier) compared to the time of entry in Kursk on October 25, and the time of sunrise shifts to a greater side (later).
