It results from subtracting the year of the hijra, stated as 622 AD, from the current year.

Any error is my own.

Answer to #19 and 20.....

It is 1425 on the muslim calendar, which is a lunar calendar.

Here's some info on calculating .........http://i-cias.com/e.o/islam_cal.htm

The Persian calendar is solar. It is year 1383.
Afghanistan may use this calendar also, but I'm not sure.
