Interpretively, this suggests sudden inspiration acted upon quickly: someone who gets a flash of insight about a journey, a cause or a creative idea and is already moving before others have caught up. Astronomically, December 11 puts the Sun near 19° Sagittarius in most years, inside the second ten-degree slice of the sign, which tradition links with Mars. Mars, ruler of Aries, acts as sub-ruler for the middle of Sagittarius, roughly December 2 to December 11. The sign's love of freedom picks up a sharper, more competitive edge. Early-December birthdays are frequently linked with bold, energetic people who are quick to champion a cause, whether on a playing field, in a debate or on the road. Their honesty may be direct enough to startle. Mars brings drive and courage, along with impatience when life moves slowly. Channelled well, this mix of vision and nerve makes for a natural pioneer, someone willing to test an idea in the real world. ## Birthday number and Life Path for December 11 Born on the 11th, you have a birthday number of 11, and because it is a master number it stays unreduced. The day of birth is a secondary number in numerology, yet master numbers are traditionally given extra weight wherever they appear. Two 1s side by side suggest doubled sensitivity as well as doubled initiative: the 11 is linked with intuition, inspiration and a nervous, creative charge. Those born on this date are often described as idealistic and perceptive, sometimes picking up on things before they can explain why. Grounding routines and trusted company tend to help them carry that intensity comfortably. Add the birth year and the picture shifts again: a December 11 birthday gives Life Path 6 for 1990, 7 for 2000, 8 for 2010 and 9 for 2020. Some birth years on this date reach the master number 22. Read the birthday number as a secondary note beside that main theme. ## Season, Chinese zodiac and famous December 11 birthdays December birthdays arrive at the start of northern winter, around the shortest days and the year's festivities, and at the start of summer in the southern hemisphere. Sagittarius holds most of the month, with Capricorn beginning around December 21 or 22. In numerology December is month 12, which reduces to 3: expression and sociability, built from the 1 and 2 of initiative and partnership. December 11 is the 345th day of the year (346th in a leap year). Counting forward, the next sign change, into Capricorn, is usually complete within 11 days, by December 22. By December 11 the Chinese new year is well under way, which means the animal and element are those of the calendar birth year. Among the best-known people with a December 11 birthday are Naguib Mahfouz (1911), Aleksandr Solzhenitsyn (1918) and Hector Berlioz (1803). ## Frequently asked questions ### What zodiac sign is December 11?
