Why it doesn't support dates before 1356(1937)?

[unknown-exception]

m = moment('1355/8/28', 'iYYYY/iM/iD'); // Parse a Hijri date. m.format('iYYYY/iM/iD [is] YYYY/M/D'); // 1410/8/28 is 1990/3/25

"1355/12/NaN is 1001/3/1"

so , i have this problem . anybody else have a solution ?

the Ummulqura algorithm doesn't includes the days before 1355AH. AFAK that if you are targeting days before 1355 is to use the Kuwaiti hijri calculation algorithm.

thanks for answer

i test now date but give wrong response

m = moment('1438/1/3', 'iYYYY/iM/iD'); m.format('iYYYY/iM/iD [is] YYYY/M/D'); "1355/12/NaN is 0000/1/1"

i change code

line 587 - 590

to

input = config._i  + '-' + leftZeroFill(date[0], 4) + '-' +
					leftZeroFill(date[1] + 1, 2) + '-' +
					leftZeroFill(date[2], 2)

worked me. maybay other function are damaged (not test)

hi, first thanks for the library. It is great :) Is there a way to use the Kuwaiti hijri calculation algorithm as part of this library? (I am looking for support for earlier dates)
