Note 915 — Chapter IX · CALENDAR REGULATION. 1. THE INTERCALATION.

I give here the English translation of Sachau, p. 73, which adds rabi I in brackets as an explanation. I am indebted to Prof. Moberg for the literal translation of the passage:—“The first nasî fell in the muharram, and safar was called by this name and rabi I by the name safar, and from this they let the months revolve in the series. The second nasî fell in safar, and the month following that (rabi I: Sachau) was again called safar, and so on, until the nasî had run through all twelve months and came back again to muharram.” As a result of the first intercalation rabi I became safar, therefore rabi II = rabi I, after the second the names are pushed another stage forwards, therefore the original safar = after the first intercalation rabi I, after the second rabi II. I have added a reference to the original situation.
