I noticed a few days back that our complimentary Ohrsom Shul in Sandton 2008 calendar does not feature Yom HaShoah on 1 May/26 Nisan; it simply appears as Workers’ Day.  I’m sure it must be an error, as the more authoritative Pick ‘n Pay calendar for 5768 2007-8 does indicate it.  I wouldn’t be surprised, though, if there’s a Black Hat conspiracy behind it.  They seem to have always had a problem with the date chosen.
