Don’t wait until January 1 to cast those big intentions into the universe! The year’s final new moon arrives in hopeful Sagittarius on December 19, the perfect time to plant seeds for your most inspired dreams.

Sagittarius new moon: December 19 (8:43PM; 28°25’)

Fresh horizons beckon as the Sagittarius new moon lands on Friday, December 19, igniting a wave of momentum around travel, education, entrepreneurship and personal growth. This is a launchpad lunation—one that invites you to think bigger, aim farther and say yes to the road less traveled.

But before you race off, make sure you’ve charted out a sensible route. As the final new moon of 2025, this one forms a challenging square to both dreamy Neptune and disciplined Saturn in Pisces, a cosmic reminder that even the most inspired vision needs a workable plan. If you want your ideas to carry you past mid-January—and beyond the “sounds amazing” phase—pair faith with follow-through.

Until December 24, Venus is along for the ride in Sagittarius, giving you a short window that’s ideal for smoothing tensions and restoring goodwill. (A blessing after last month’s Mercury retrograde mischief.) Mend misunderstandings with a sweetened dose of truth serum. Honesty is always the best policy where Sagittarius is concerned. Just remember: Savvy timing and tact help the raw data go down smoother.

Intentions set at the Sagittarius new moon benefit from a wide-angle lens

Whatever intentions you set under this new moon, switch to a wide-angle lens. Exploration and expansion are favored this December 19. That means: whether you’re daydreaming about Perth, plotting Portugal or scouting the perfect winter escape, it’s smart to cast an even wider net. Broaden your search radius a few extra miles. You could uncover a hidden-in-plain-sight option that your future self will thank you for.

Enterprising types: don’t let the looming holiday break derail your ambitions. The Sagittarius new moon delivers a dose of “cosmic capital” for startup energy. What milestones would you love to hit over the next six months? One small, intentional move now can send a powerful message to the universe that it’s Go Time for an ingenious idea.
