The
Islamic calendar is different to the one used in Western countries. Their "Year 1" was in 622 AD, but their year is based on the lunar cycle, and is 354 days long.
To convert Islamic "Anno Hegira" (AH) dates to Western (AD) dates, you can use the table provided in the Krause catalogues, or you can type a year into a calendar conversion website like
this one and let it do the conversion for you.
Note that the countries of north-west Africa (Morocco, Algeria, Tunisia) use "Western-style" numerals to write the date on the coins. This can cause some excitement among beginner collectors, who find a "really old coin from the 1300's" in a scratchtray. Most other Muslim countries use
Arabic numerals.
Also note that Iran and Afghanistan use a
different calendar, the "Solar Hegira" (SH) where year 1 is the same (622 AD) but the years are "normal length".
Sorry for rambling on. Collecting coins which feature the different calendars used in various parts of the world is a sub-theme I'm developing.

(Edited because I seem to have trouble spelling. "Afgahnistan", indeed!
