Dated rug
A dated rug has a year woven into it, often beside a signature. Identify the calendar before converting it: older Persian inscriptions often use lunar Hijri years. For a rough Gregorian year, multiply a lunar year by 0.97 and add 622; for solar Hijri, add about 621. Exact conversion depends on the month and day. An inscription needs interpretation alongside the rug itself.
