Quote from http://en.wikipedia.org/wiki/Ascension_of_Jesus:
"The Feast of the Ascension, celebrated on the 40th day of Easter (always a
Thursday), ...."

There are calculation differences between eastern and western churches
(http://en.wikipedia.org/wiki/Feast_of_the_Ascension) but for Indonesia, I
wrote it in holiday_id_en-us as:
: Kenaikan Yesus Kristus
"Ascension Day"                          weekend on easter plus 40 days

That resulted in the holiday falls on the 41st day of easter (Friday May 18,
2012). Officialy, in Indonesia, this year's Ascension day is Thursday, May 17,
2012.  When I check other holiday files (grep -lir ascension
/usr/share/apps/libkholidays/plan2/), there are three version of the holiday.
Those who use "easter plus 39 days" (it falls on Thursday. I assumed this is
the correct date)
- holiday_at_de
- holiday_wf_fr
- holiday_re_fr
- holiday_ch_fr
- holiday_nc_fr
- holiday_yt_fr
- holiday_gt_es
- holiday_gt_fr
- holiday_gp_fr
- holiday_lu_fr

Those who use "easter plus 42 days" (It falls on Sunday, which according to
http://en.wikipedia.org/wiki/Feast_of_the_Ascension#Sunday_observance is
correct)
- holiday_it_it
- holiday_sm_it
- holiday_nz_en-gb

Those who use "easter plus 40 days":
- holiday_us_en-us
- holiday_pt_pt
- holiday_na_en-gb
- holiday_id_id
- holiday_id_en-us

Now I cannot be sure about other country's holiday, but for Indonesia the
correct holiday should use "weekend on easter plus 39 days". I'll attach the
correct Indonesian kholiday files. 


Reproducible: Always

Steps to Reproduce:
1. Open calendar (with Indonesian holiday activated)
2. Search for Ascension Day 

Actual Results:  
It falls on Friday

Expected Results:  
It should be Thursday
