Apparently there is some confusion about a solar day and a sidereal day. Wikipedia gives these numbers:
[A] Venusian day is 116.75 Earth days long, about half a Venusian solar year, which is 224.7 Earth days long.
That, of course, confused me. Further research showed that 116 days is a solar day, when the sun is at the same place in the sky again. But a sidereal day, when the planet completed a rotation on its axis, is indeed 243 Earth days.
