Ad Tech SF Conflicts with Passover

An alert reader this morning alerted me to the fact that Ad Tech's San Francisco show kicks off on April 25th. Passover starts at sundown on Saturday, April 23rd and this presents a problem for Jewish ad industry professionals who want to get into town on Sunday per the usual practice but don't want to miss the second night of Passover. One wonders how this was overlooked by the folks scheduling the show.
