Accuracy

The lunation number is a simple calculation of time since the epoch divided by the average lunar cycle length. As the lunar cycle can vary by several hours, the time that the lunation number changes might not exactly match the current lunation. It is mostly intended to be used as an approximate reference rather than as a rigid definition of when the lunation has occurred.
