Solar and lunar eclipses are always active in predicting when a person will get married. They will highlight certain areas in the natal chart the year or two years prior to as well as the actual year of marriage. The 2-3 eclipses after marriage can also activate the same areas. The pertinent areas include factors related to the 7th house, because that house represents marriage.
Solar and lunar eclipses falling on the 1st-7th house axis as well as eclipses making tight aspects to the planets ruling the 7th house, placed in the 7th house, being the dispositor of the 7th house, or planets in the 7th house can also signal marriage. Keep in mind that the transits, secondary progressions and solar return must also show the same theme. For the six examples below, I will just describe the triggering eclipses of the marriage, and the full list of eclipses can be found at http://www.cafeastrology.com/eclipsessolarlunar.html
Barack Obama got married to Michelle Robinson on October 3rd 1992:
Matt Damon got married to Luciana Barroso on December 9th 2005:
Tom Hanks got married to Samantha Lewes on January 24th 1978:
Prince William got married to Kate Middleton on April 29th 2011:
Sean Penn got married to Madonna on Aug 16th 1985:
Justin Timberlake got married to Jessica Biel on October 19th 2012:
We see from these case studies that before every marriage there must be eclipses to trigger it, this is often three or more eclipses making tight aspects to the 1st-7th axis houses as well as making tight aspects to the planets ruling the 7th house, placed in the 7th house or being the dispositor of the 7th house or planets in the 7th house. All through the years of my study and practice, I have never seen a marriage happen without the triggering eclipses. So the next time you are asked to predict if there is a marriage on the way, be sure to check the powerful predictive tool of solar and lunar eclipses!
