I created two text fields.

Islamic & English fields.

When i enter hijri date in Islamic field. Automatically convert into english and display it in English field.

I got a code from the forum, but it throws error. Below is my code.

from openerp.osv import fields, osv import math

def intPart(floatNum): if floatNum < -0.0000001: return math.ceil(floatNum - 0.0000001) return math.floor(floatNum + 0.0000001)

def Hijri2Gregorian(yr,mth,day): jd1 = intPart((11 * yr + 3) / 30.0) jd2 = intPart((mth - 1) / 2.0) jd = jd1 + 354 * yr + 30 * mth - jd2 + day + 1948440 - 385

if jd > 2299160:
   l = jd + 68569
   n = intPart((4 * l) / 146097.0)
   l = l - intPart((146097 * n + 3) / 4.0)
   i = intPart((4000 * (l + 1)) / 1461001.0)
   l = l - intPart((1461 * i) / 4.0) + 31
   j = intPart((80 * l) / 2447.0)
   d = l - intPart((2447 * j) / 80.0)
   l = intPart(j / 11.0)
   m = j + 2 - 12 * l
   y = 100 * (n - 49) + i + l
else:
   j = jd + 1402
   k = intPart((j - 1) / 1461.0)
   l = j - 1461 * k
   n = intPart((l - 1) / 365.0) - intPart(l / 1461.0)
   i = l - 365 * n + 30
   j = intPart((80 * i) / 2447.0)
   d = i - intPart((2447 * j) / 80.0)
   i = intPart(j / 11.0)
   m = j + 2 - 12 * i
   y = 4 * k + n + i - 4716

return y, m, d
