Obseesed with Sunset Times

My wife Mary loves to take sunset and sky pictures!

Since I am now an ardent student of sunset times, I have learned that sunset times change much slower in the winter than in the summer at this latitude.
Sunset for this town is at 5:10 pm today on November today on November 17. On the shortest day of the year, Winter Solstice, the sunset time is 5:05, a difference in a month of only 5 minutes.
It seems in the Spring and Fall the sunset times change at least a minute a day. I keep track of these times daily so Mary and I can be where we want to be at sunset. I learned while tracking these times that knowing one day what the sunset time is not necessarily valid several days into the future.
Looking forward to Daylight Savings Time, not because I think it's a good idea (I don't) but because sunset will be at 7:30 PM.
My daughter Rebecca mentioned that one of the Equator countries the sunset and sunrise times are 5:30, year round. That sounds 1. weird. 2. boring. 3. nice.
By the way, the Google Weather app on my Android phone has daily sunset times. Who knew?
