Gregorian-Hijri Dates Converter

Former Member — Tue, 25 Apr 2006 12:55:59 GMT

Hello Experts;

I am looking for ABAP Report/Function module for "Gregorian <=> Hijri Dates Converter".

Any assistance in this regards would be highly appriciated and points will be rewarded.

Looking forward for your usual prompt and professional advice...

Best Regards,

Aslam

You may ask... What is Hijri Calender?

<a href="http://en.wikipedia.org/wiki/Hijri">en.wikipedia.org/wiki/Hijri</a>

The Islamic calendar or Muslim calendar (also called "Hijri calendar", Arabic) is the calendar used to date events in many predominantly Muslim countries, and used by Muslims everywhere to determine the proper day on which to celebrate Islamic holy days. It is a lunar calendar having 12 lunar months in a year of about 354 days. Because this lunar year is about 11 days shorter than the solar year, Islamic holy days, although celebrated on fixed dates in their own calendar, usually shift 11 days earlier each successive solar year, such as a year of the Gregorian calendar. Islamic years are also called Hijra years because the first year was the year during which the Hijra occurred— Muhammad's emigration from Mecca to Medina. Thus each numbered year is designated either H or AH, the latter being the initials of the Latin anno Hegirae (in the year of the Hijra).

Hi,

Check out this site

http://www.altawfeek.com/hijcon.htm

they javascript to do the conversion. view the source of the page and check out the js functions

GregToIsl and

IslToGreg

you can come up with the same logic in ABAP or create a html template with those javascripts and present them in a html container within sapgui

Hello Aslam,

I dont think SAP provides such function module..

You can refer to the above site given by Raja and do the implementation of the logic in ABAP..

Tanveer.

Hi,

use the below sub-routines in ABAP to convert Gregorian to Hijri dates and vice versa

WF_RESULT2 TYPE C,

WF_DATE1 TYPE SY-DATUM,

WF_DATE2 TYPE SY-DATUM.

*WF_DATE1 = '14271123'.

PERFORM F_GREGORIANTOHIJRA1 USING WF_DATE1

CHANGING WF_DATE2.

WRITE:/ WF_DATE1,WF_DATE2.

PERFORM F_HIJRATOGREGORIAN1 USING WF_DATE2

CHANGING WF_DATE1.

Very close, but the conversion is not accurate on 2008/11/01 due to a one day shift. It is a bit more complex than a mathematical computation. Once a year the start date is determined.

Hi, Aslam,

It is is not working fine.

25.06.1434 = 06.05.2013 it is wrong.

25.06.1434 = 05.05.2013 it is Correct.

Please give me a solution for that issue.
