Since 1 AD, a "Biblical tetrad" has occurred on these holy days a total of 7 times. In 2014-2015, it will be the 8th time. It won't occur again for another 500 years.
Are we going to witness some crazy things on the market due to this event? Sometimes astronomy (and astrology) should not be dismissed as they can have more than simply a coincidental occurrence with events (both financial and otherwise).
