One of the features/calendars that Moon Tracks provides is the Personal Power Days updated each month. These charts show the best days for each solar sign to act in relation to the Moon's transits. This chart also reveals the days that a particular solar sign is less likely have be "on target" giving clues as to which dates are best for pushing forward on a project and which days to hold back a bit.
As always, these are general charts since the actual natal chart for an individual will give us the best clues for dates of acting. A great way to find out more about your personal power days is to check out the DayWatch Calendars at lunarliving.org on the orders/store page.
