Certain authors caution against identifying "day" with rotation period. For example: Seligman, Courtney. „Rotation Period and Day Length”. Приступљено 3. 6. 2011. „A Cautionary Note: Because the rotation period of the Earth is almost the same as the length of its day, we sometimes get a bit sloppy in discussing the rotation of the sky, and say that the stars rotate around us once each day. In a similar way, it is not unusual for careless people to mix up the rotation period of a planet with the length of its day, or vice versa.”

Дан, "Хрватска енциклопедија", Лексикографски завод Мирослав Крлежа, www.enciklopedija.hr, 2015.
