Hello, thank you! That option already exists: On the website version, it's available in the "Henge Near Me" tab. You can toggle between Sunrise and Sunset.

There are more features on the mobile version, and it also includes Sunrise and Sunset. Just hit the gear icon on the top right, and toggle between Sunrise and Sunset. Hope that helps!

This looks good and now I think my memory was about 180 degrees off, in Houston it must have been the winter solstice when I saw this one morning.

Your app gets very close but not quite there on the 22 DEC inflection point, I would think the date is correct but the angle is a couple degrees short when the limit is approached. At this latitude it looks like the effect is visible for a day or two before & after the closest alignment.

I'll be checking when the time comes but I was hoping it was only going to be a month from now :\
