♐ Sagittarius Weekly Horoscope
December 15 to December 21, 2025
Written by Mia Astrology
“Sagittarius, this week helps you shift from thinking about your goals to actually building the structure that supports them.”
The week opens with an important change. On December 15 Mars moves into Capricorn, activating your second house of money, stability, values, and long term security. Mars in this area helps you take financial decisions more seriously. You might feel more responsible, more organized, or more determined to create stability for your future.
This placement does not create drama. It simply motivates you to be more intentional with your time, effort, and resources.
The Sun, Mercury, and Venus remain in Sagittarius for most of the week, so you still feel social, expressive, and open. This gives you the confidence to speak your mind and make decisions that reflect who you are right now rather than who you used to be. You may feel more connected to your identity and more willing to be honest about what you want.
This combination is useful. Sagittarius energy helps you see the bigger picture. Capricorn energy helps you take the realistic steps required to get there.
Jupiter is retrograde in Cancer, making emotional boundaries and shared resources a point of reflection. You may be reconsidering how much you give, how much you receive, and whether your emotional investments feel fair. This retrograde helps you identify what supports your long term wellbeing.
In relationships, this is a week for practical conversations rather than emotional intensity.
If you are partnered, you may talk about finances, future goals, or shared responsibilities. These discussions help you feel more aligned.
If you are single, you might notice a shift in what you find attractive. Stability becomes more important than excitement.
At work, Mars in Capricorn helps you focus on value. You may rethink your pricing, work habits, time management, or financial goals. This is a strong week for organizing your income stream or planning a financial improvement.
On December 21 the Sun enters Capricorn, doubling the focus on stability and long term growth. This marks the beginning of a period where your attention turns toward building a stronger foundation for next year.
Sagittarius, this week encourages you to combine confidence with practicality.
You are not giving up your dreams.
You are organizing them so they can become real.
This week supports you in creating stability that matches your long term goals.
