1401, not 1400

The Muslim calendar, like the Christian calendar, starts with Year 1. Neither civilization had the number 0 at their origins and numbered years ordinally, i.e. 1st, 2nd, 3rd... 2000 A.D. was the last year of the 20th Century. 2000 years of the era had not elapsed until the end of that year and the 21st Century/3rd Millennium began with 2001. Likewise, at the start of 1400, only 1399 lunar years had passed since the Hijra and the 15th Islamic Century began with 1401 A.H.

I want Constantinople back.
