Islamic-Gregorian date converter

In response to my earlier query on this, Reidar Visser sent me this handy link, which is to a site that automatically does either Gregorian-to-Hijri (Islamic) or Hijri-to-Gregorian calendar conversion.
A linked page there contains this listing of the various, lunar-based, Hijri months:

(1) MuHarram
(2) Safar
(3) Raby` al-awal
(4) Raby` al-THaany
(5) Jumaada al-awal
(6) Jumaada al-THaany
(7) Rajab
(8) SHa`baan
(9) RamaDHaan
(10) SHawwal
(11) Thw al-Qi`dah
(12) Thw al-Hijjah
The most important dates in the Islamic (Hijri) year are: 1 MuHarram (Islamic new year); 27 Rajab (Isra & Miraj); 1 RamaDHaan (first day of fasting); 17 RamaDHan (Nuzul Al-Qur’an); Last 10 days of RamaDHaan which include Laylatu al-Qadar; 1 SHawwal (`iyd al-FiTr); 8-10 Thw al-Hijjah (the Hajj to Makkah); and 10 Thw al-Hijjah (`iyd al-‘aDHHae).

So, using the converter, I can now tell you that the next of those liturgical-calendar dates that is coming up is the 27th of Rajab 1427 which is…. 22 August 2006 CE (with a small probability of a one-day error, depending on moon-sightings.)
Handy, huh?
