Is there any public database similar to tzdata encoding workweek/weekend transitions over time?<br><br><a href="http://en.wikipedia.org/wiki/Workweek_and_weekend">http://en.wikipedia.org/wiki/Workweek_and_weekend</a><br><br>
I am asking the folks on this list because the transitions sound eerily like DST transitions:<br><br>&quot;The coalition government formed on December 2011 issued a decree 
changing the weekend in Yemen. As of February 2012 the weekend in Yemen 
will be Friday–Saturday [instead of Thursday–Friday].&quot;<br><br>-Andrew<br>
