We’d like to hum a rousing chorus of “Shine on, Harvest Moon,” but the vibes are off. Luna’s spectacular, a true harvest moon. But come Tuesday, the sun and moon confront mean old Saturn. The celestial message is to accept responsibility for past actions.

Aries (March 20-April 18) The full moon in your sign eyeballs the sun and Mercury in Libra as you stand at a midpoint in your life. It’s six months since your last birthday. Isn’t it time for a decision or two, maybe even a change?

Taurus (April 19-May 19) Lunar beams bring a moment of truth regarding money — your money — while Jupiter’s current mandate is to speak up for yourself in one-on-one relationships. Walk softly and carry a calculator.

Gemini (May 20-June 19) Is a friend or colleague pulling the strings where personal communications are concerned? Long-term pursuits such as travel and higher education are involved. Sooner or later you’ll have to confront the issue.

Cancer (June 20-July 21) Other people’s mood swings test your patience. The good news is that you’re learning important lessons. Now, here’s the full moon with a message to speak up for yourself at home as well as in the great world.

Leo (July 22-Aug. 21) Expect an amatory problem to unkink itself as an upsy-downsy week moves toward a — dare we say? — climax. You’re going to be doing what a Leo does best — pushing the envelope as far as it will go.

Virgo (Aug. 22-Sept. 21) You’re a work in progress, changing all the time. Though your introspective side appreciates a little down time, the rest of you is dreaming of wild-side walks. Treat both “sides” to a nitty-gritty pleasure.

Libra (Sept. 22-Oct. 21) The week ahead contains both drama and opportunity. Tuesday’s decision involves a partner. Possibly money’s involved. Sound interesting? There’s also a chance for intimacy. If you weren’t one of those balanced Libras, I’d think you were about to walk on the wild side. Scorpio (Oct. 22-Nov. 20) Something you’d begun to think impossible morphs into no problema. Perhaps a mistake was discovered — in your favor. With the full moon in your house of joint funds, anything can happen.

Sagittarius (Nov. 21-Dec. 20) You’re the master when it comes to building networks and causeways to fame and fortune. Now, with the full moon ruling the roost in your travel house, it’s time to go out, see, be seen.

Capricorn (Dec. 21-Jan. 19) You’re in the right place at the right time doing the right thing. Now, while the full moon does the glitter thing in your fame house, you’re ready to move ahead on a “not what you know but whom” scheme.

Aquarius (Jan. 20-Feb. 17) Expect only the unexpected. Sweet nothings will be shouted rather than whispered. Proposals may sound suspiciously like propositions. But, whichever way the sugar cookie crumbles, you have the creative chops to play it your way.

Pisces (Feb. 18-March 19) As the full moon blasts your “house of drawn shades,” the past comes into clearer perspective. You’ll take that insight into winter and spring. We’re talking financial issues where cooperation makes the difference.

Q: I’m an Aries male madly in love with a Libra female. What are our chances of a life together?

A: At first, she’ll be only too pleased to play the feminine charmer in exchange for your decisiveness. Very few disputes will occur on the way to the bedroom. It’s on the way to kitchen, den or living room that things can get rocky. At first she’ll love your decisiveness, but eventually Lady Libra will want to make her own decisions. Then it’s time for a lusty Ram like you to take a cram course in charm.
