The sun and moon square off today at the moon's last quarter, perpetuating the desire to throw off old patterns and move ahead. The obstacles we face, or the people blocking our way, may actually be more like the windmills that Don Quixote mistook for invisible giants. If we're tilting at windmills, a shift in our thinking sets us straight.

ARIES (March 21-April 19). When nothing is going wrong, enjoy! Sure, you still have the mental resources necessary to give yourself a good scare. But why? Inventing problems is one creative process you can do without.

TAURUS (April 20-May 20). What we learn from "The Wizard of Oz" is that sometimes a person must leave home in order to appreciate it. This is the perfect day to buy your ticket, especially if your trip isn't for a couple of months.

GEMINI (May 21-June 21). Wise choices you made in the past will continue to support you. This is especially true in business. People on your team are smart enough to handle whatever business you throw their way, so delegate.

CANCER (June 22-July 22). You take complete responsibility for the impression you make on others. Know what you want to say and how you want to portray yourself. Soon you have a constituency of supporters.

LEO (July 23-Aug. 22). You are your word. But what about the situation where you didn't actually say anything directly, maybe just implied it? Make good on those implications and the people you're dealing with will not only trust you but also love you.

TODAY'S BIRTHDAY (Feb. 28). This year, you become stronger and more flexible on all levels — mental, physical and spiritual. Loved ones join you on your quest for improvement. Slim down your schedule in May or too many obligations could stunt the flow of opportunity. Money luck makes for a June adventure. Relationship commitments happen in July. Virgo and Libra adore you. Your lucky numbers are: 6, 11, 30, 16 and 52.

VIRGO (Aug. 23-Sept. 22). You're forging an even stronger connection with that person who makes you laugh. (Taurus and Capricorn fit the role). Together, you'll find solutions for today's strange and random problems.

LIBRA (Sept. 23-Oct. 23). Your physical body is strongly affected by your general attitude toward it. Look in the mirror, and give yourself the wink and nod of approval. Even better, go in for a pep talk. It will improve your health.

SCORPIO (Oct. 24-Nov. 21). Everything is easier. People are more accessible.

The wheels of innovation and productivity spin a little faster. People just seem to "get" you. You're in the zone, so work it.

SAGITTARIUS (Nov. 22-Dec. 21). You're in a generous mood. Maybe too generous for those close to you. Don't, as they say, give away the farm without considering how others (including the cows and chickens) are going to feel about it.

CAPRICORN (Dec. 22-Jan. 19). You're trying out different ways to express yourself. The planets suggest that now is your chance to be nutty. Be weird. Mess up! And you'll have so much success with this that you may decide to make it a lifestyle.

AQUARIUS (Jan. 20-Feb. 18). Your mission is one of outreach. Through the phone and the Internet, you spread good vibes to corners of the globe — or at least the country. Don't hold back. Be mushy. Loved ones long to hear it.

PISCES (Feb. 19-March 20). Don't know if you're coming or going? Try to think like a drop of water. Whether it's frozen solid as ice, floating on air as steam or in its natural, liquid form, water is infinitely adaptable. Change is good.

ASTROLOGICAL QUESTIONS: "I'm curious about those born on Feb. 29. Do they only get to celebrate their birthday once every four years?"

Here's the skinny on leap-year babies: They age four times slower than the rest of us. Kidding! But seriously, what is a birthday? Convenience ties it to a calendar day, but the exact date/time the sun returns to the position it held when you were born is your real birthday. And because the Earth adds a little pirouette to each passing year, no person's anniversary of birth is ever quite the exact day or time he or she was born. Any astrologer can give you your solar birthday, or you can do it yourself by adding 365 days, five hours, 48 minutes and 46 seconds to each passing birthday, starting with your very first. For example, if you were born on Feb. 29, 2008, at 12:48 p.m., your next birthday (the return of the sun to its original position when you were born) is Feb. 28, 2009, at 6:36 p.m. You'd turn three on March 1, 2010, at 12:32 a.m., and so on. But in 2012, a leap year, your birthday would return back to Feb. 29, around noon.

CELEBRITY PROFILES: Pisceans can add shrewd business skills to their manifold attributes. For her unfolding consulting career, Chelsea Clinton draws on her sun sign's ability to work selflessly for others, handy for clocking long hours at the office and giving her all to a heartfelt cause. Self-organization is a typical challenge for Pisces, but Chelsea's Saturn in Virgo creates method out of madness.
