August 15 is day 227 of the year (228 in a leap year). The Sun is then roughly 24° into Leo, 8 days before it moves into Virgo, which places your birthday in the third of the sign’s three decans.
Leo, third decan
Leo’s final decan carries the fiery boldness of Aries, and Mars adds its pulse to your Sun-ruled heart. You are Leo with a sprinter’s pulse. You tend to act on inspiration immediately, champion underdogs, and take charge when others hesitate. Confidence and courage fuse in you, making you a natural pioneer. Patience may not be your favorite virtue, and your temper can flare quickly, yet it fades just as fast. People admire your bravery and your fierce, protective loyalty.
Born on the 15th: birthday number 15
With a 15th birthday, the independence of one meets the adventure of five, adding up to six, the number of love and home. You tend to be magnetic, generous, and artistic, and people feel welcome in your company. Your home is often a gathering place. Despite your love of comfort, you have a free spirit that resists being told what to do. Balancing your caretaking instincts with personal freedom is your central theme.
1 + 5 = 6: The Nurturer. A 6 birthday tucks warmth, responsibility and a love of home into the life path you walk. Numerologists reach that path by reducing the full birth date — year included — to one digit. The answer shows whether caretaking sits at the center of your path or flavors it from the side.

Your birth tarot cards
Strength, the card of Leo. The pairing is almost literal: a figure calmly holding a lion’s jaws shows courage that comes from warmth, not force. The Golden Dawn saw in it the sign’s big heart, confidence and gentle command.
Seven of Wands, the card of your decan (Mars in Leo in the Golden Dawn system). Stand firm for what matters, but don't waste strength on battles that don't.
The Devil, the card of your day number. Read gently, it speaks of magnetism, ambition and an honest relationship with desire. Its quieter point is that the chains on the card hang loose, so most habits that bind can be lifted off. Name what has a hold on you; naming it is the beginning of freedom.
The card of your whole birth date, year included, comes from the tarot birth card calculator.
Strengths and challenges
Strengths: bold initiative, fierce protectiveness, magnetism, generosity. Growth edges: quick temper and possessiveness.
Love and compatibility
In love you are passionate, direct, and loyal. You enjoy pursuit and admire a partner with confidence of their own. Conflicts can heat up quickly, so cooling down before speaking helps keep your romance spirited rather than combative.
Charming and affectionate, you attract admirers easily. You want a relationship that feels like a cozy home base without walls closing in. Generosity flows naturally, but avoid trying to manage your partner’s happiness.

Career and purpose
Athletics, entrepreneurship, emergency services, sales, performance, and any leadership post with a pulse suit your competitive streak. You lead from the front. Choose roles with clear challenges and room for initiative, and learn to delegate without losing momentum.
Warm creativity like yours finds a home in hospitality, design, the arts, teaching, and wellness businesses. You often succeed when your work beautifies or supports people’s daily lives. Your charm opens doors; follow-through keeps them open.
