Planetary movements this month (the basis)
The main planetary movements in December 2026 are as follows. Mercury, the ruling planet of Gemini, moves from Scorpio into Sagittarius on December 6, and into Capricorn on December 26. There is a new Moon in Sagittarius, opposite Gemini, on December 9. The Sun is in Sagittarius until December 22, and then moves into Capricorn. Uranus also stays in Gemini throughout December, and a placement that keeps sensitivity to change high continues.
Overview
This is a month when information flows fast and interests shift easily. In the first half, with a new Moon in opposite Sagittarius, there are more situations where you take in other people's words and outside information and rebuild your own thinking. The conclusion for this month is not to increase the information you have gathered, but to separate what to decide within the year from what to carry over to the New Year. When Mercury moves into Capricorn at the end of the month, decisions settle in a practical, steady direction.
Work
The central task is organising scattered information and deciding where the lines of responsibility fall. In the first half, messages and consultations increase, and matters spread easily. For example, if you list the progress of the cases you are carrying and share it, talks about handovers and sharing work become easier to move forward. Others will see the speed and breadth of your information, but it is also a time when you can easily give the impression that your conclusions are not settled. For important matters, putting what you have decided briefly in writing leads to a better reputation. In the second half, the Sun and Mercury move into Capricorn, and talks to firm up next term's structure and roles become central. Rather than adding new matters, the right approach is to hand over what you have decided without fail. For matters you cannot fully decide within the year, share at least when you will decide them, and you will not be caught off guard when the matter comes back in the New Year.
Money
This is a month when spending related to information and tools stands out. The central decision is separating spending needed for work from spending on things your interest has moved away from and you no longer use. At the year-end break, list and review once the payments that continue each month, such as communications, books and tools. The point this month is to keep only the spending directly linked to next term's work, and to stop payments whose role has ended. For large purchases, the period at the end of the month when Mercury moves into Capricorn is better for checking the terms calmly.
Health
This is a month when time spent with information is long and mental tiredness easily remains. This does not go into diagnosis or treatment of physical problems, but the point to watch this month is to secure rest days in your schedule in advance. Measures within the range of daily life, such as limiting screen time before bed, suit this month.
Love
This is a low-key section. Keep in touch regularly about year-end plans, and misunderstandings will decrease. Even for a light promise, fix the date and time clearly and you can relax.
