When do event dates like "close registration" take effect?
EventHQ allows you to set important dates in the lifecycle of your event, upon which EventHQ may act, e.g. to open/close registration automatically.
EventHQ will take action at midnight in your account timezone on the date you specify. For example, if your account timezone is UK (GMT) and you set a "close registration date" of 1st November 2015, EventHQ will effectively close registration at 23:59 on October 31st 2015.
