"It is of the creative events that took place on each of these 'days' that we shall now speak. But first, what is a day? It is a specified time period; it is an age, an eon, a division of eternity; it is the time between two identifiable events. And each day, of whatever length, has the duration needed for its purposes. One measuring rod is the time required for a celestial body to turn once on its axis. For instance, Abraham says that according to 'the Lord’s time' a day is 'one thousand years' long. This is 'one revolution … of Kolob,' he says, and it is after the Lord’s 'manner of reckoning.' (Abr. 3:4.) There is no revealed recitation specifying that each of the 'six days' involved in the Creation was of the same duration. Our three accounts of the Creation are the Mosaic, the Abrahamic, and the one presented in the temples. Each of these stems back to the Prophet Joseph Smith. The Mosaic and Abrahamic accounts place the creative events on the same successive days. We shall follow these scriptural recitations in our analysis. The temple account, for reasons that are apparent to those familiar with its teachings, has a different division of events. It seems clear that the 'six days' are one continuing period and that there is no one place where the dividing lines between the successive events must of necessity be placed."
