Double transit: the houses from the lagna that transit Jupiter AND transit Saturn both occupy or aspect on transit_date (classical graha drishti: Jupiter sees the 5th, 7th and 9th from itself, Saturn the 3rd, 7th and 10th), the houses whose LORD's natal house both planets touch, and the upcoming windows per house found by monthly sampling over months_ahead. Lasting events (marriage, promotion, property, a child) are read where both planets agree. House lords follow the reading lordship (Ketu for Scorpio, Rahu for Aquarius); traditional_lord is given.
