Gemini, decan 1
Sub-ruler: Mercury
With Mercury doubled, this is Gemini at full speed: quick wit, quick questions, three tabs open in your head at once. You learn by talking and you talk to think, so conversations with you tend to go somewhere unexpected and interesting. Almost nothing bores you for long, and that curiosity keeps you young. Scattering is the price, starting five things and finishing one, or changing your mind before anyone caught up with the first version. Pick one project a week to actually complete. A partner who enjoys the banter suits you, as long as you remember to listen as well as talk.
Birthday number 3
Words, color and laughter follow you around. This number belongs to storytellers, hosts and anyone who can turn a dull afternoon into an event. You think out loud, make friends in waiting rooms and have more ideas before lunch than some people have in a week. Creativity is your natural currency. The flip side is scattered energy: five half-finished projects and a dozen open tabs. Pick one thing to complete this month and give it your full voice. Finished work carries your talent further than promising starts.
Born in May
Gardens are at their fullest in May, and the month’s children often have a grounded warmth to match. Taurus covers roughly the first three weeks, lending loyalty, patience and an appetite for comfort, good food and lasting things. Gemini arrives around the 21st and lightens the mix with wit, curiosity and a gift for conversation. Emerald, the vivid green birthstone, has symbolized rebirth and love for centuries. Lily of the valley is the birth flower and a traditional sign of happiness returning. Many May people are the ones friends call when they need a good meal and a good laugh.
