Subject: 28.0.50; Wrong sunrise and sunset here
Date: Tue, 26 May 2020 18:25:52 +0300

The sunrise here is about 7 A.M. and sunset about 7 A.M. but don't know
exactly. I have set the location and time zone and things correctly, and
I get really incorrect answer from the function.

(setq calendar-latitude 29.72780)
(setq calendar-longitude 1.12484)
(setq calendar-time-zone 180)
(setq calendar-location-name "Bwindi Impenetrable Forest")
(setq calendar-standard-time-zone-name "UTC+180")

Sunrise 7:58am (UTC+180), sunset 9:47pm (UTC+180) at Bwindi Impenetrable
Forest (13:48 hrs daylight)

That answer is not quite right, sunset is never 9:47pm, but also not 8pm
it is about 7pm and sunrise is about 7am, every day about the same with
slight differences during the year. Sunrise is about 1 hour too much,
and sunset almost 3 hours, so it makes no sense.

You seem to have mixed up longitude and latitude.
It is unlikely somewhere 1 degree east of the meridian is 3 hours ahead
of UTC.

Ah, thank you, I have mixed the latitude and longitude and did not put
it negative for latitude.

$ termux-location -p gps

{
  "latitude": -1.12455759,
  "longitude": 29.72765716,
  "altitude": 1825.0,
  "accuracy": 18.0,
  "bearing": 287.3999938964844,
  "speed": 1.9112823009490967,
  "elapsedMs": 6,
  "provider": "gps"
}

Now it is showing me pretty correctly:

M-x sunrise-sunset

Sunrise 6:57am (UTC+180), sunset 6:59pm (UTC+180) at Bwindi
Impenetrable Forest (12:02 hrs daylight)

Thank you,
Jean
