in the west as Venus spins retrograde (opposite) relative to the earth's movement. The period of rotation of Venus (a Venusian day) is longer the Venusian year by 18.3 days. Venus circles the sun every 224.7 earth days, but spins itself every 243.5 earth days, so a venusian alien would have two birthdays in any 1 year and if you went to bed at dusk would get a great lie in!!

In the west. Venus spins backwards.

To the west. Venus spins in a way that is called retrograde or short for moving backwards from earth.

Uranus moves in a retrograde system but addition to that, it spins on its side.

The sidereal rotation period of Venus is 243.019 Earth-days = 5832.456 hours; backwards. This means that the stars (sidereal) rise in the West and would appear to move towards the East at a rate of 0.0617 deg. per hour. By comparison, from Earth, stars appears to move from East to West at 15.025 deg. per hour.

Of course, the observer on Venus would need special instruments (radiotelescopes, perhaps?) to see the apparent rotation of her celestial sphere (because of the clouds in the atmosphere of Venus).

Venus goes around the Sun in 0.6152 Earth-year = 224.7 Earth days = 5392.73 hours. Because Venus orbits the sun in the "normal" direction (meaning: same direction as us -- counter-clockwise when seen from above the Sun's north pole), the Sun will appear to move eastward relative to the stars: 360 deg. in 5392.73 hours = 0.06676 deg./hour.

The Sun's apparent movement, for an observer on Venus, would then be:
0.0617 deg. per Earth-hour for the stars, PLUS
0.0676 deg. per Earth-hour relative to the star, EQUALS

0.1293 deg. per hour for the Sun relative to the observer.
Eastward (since both movements are eastward).

Like on Earth, the time from Sunrise to Sunset may change with the observer's latitude and the Sun's declination. For an observer on the equator of Venus, the approximate time from theoretical sunrise to sunset (duration of 180 degrees) would be 1392.11 Earth-hours (and the theoretical night would be the same length).

2784.22 hours from one Sunrise to the next.
5392.73 hours in a Venus-year.
1.9369 sunrise per year.

There would be 2 sunrises in most "years" (97% of the time).

If you have breakfast just after sunrise, then lunch will be at "noon", almost 700 hours later (= 29 Earth days).
