Sun conjunct Jupiter indicates general harmony in the geocentric world chart, although other transiting alignments of planets might offer conflicting conditions. Anything started today will have a new chart and that new chart would inherit this harmonious alignment. If you are having some negative personal transits starting something on these dates (or the three days on either side) might not be quite as good for you, but if you are having personal green lights these dates can be superlative.
The date an aspect becomes exact is marked on the calendar, but remember that the peak activity can extend to three days BEFORE and sometimes even up to three days AFTER the aspect is exact. We set the date on the calendar for Eastern Standard Time (NY time/ UTC -5 hours) so there may be time discrepancies in different time zones.
NOTE: Only the most significant transiting conditions are included on this calendar. For precise planning of crucial activities your own transits and other planetary geometry should be considered.
