The Time Period Between the Hijri and the Christian Calendars
 

What is noteworthy here is that someone accused me of confusing, according to his claim, the Hijri, in as far as his age is concerned, with the Christian calendar which he meant in his statement about determining the meeting year with regard to Sayyid Sharafud-Din. We say that it is quite obvious that every 33 Christian years increase the Hijri calendar by one single year. The theory invented by the claimant cannot solve the problem of the terms to which we made a reference because the difference is quite big and because the number of years between both ends is quite large, and it is defined by words and letters, not by figures.
