May zodiac signs

May birthdays fall in Taurus or Gemini. Pick a day for its sign, the Sun’s exact degree and decan, and a short profile.

Taurus and Gemini

May belongs to two signs. Taurus holds the first two thirds of the month, and the Sun changes into Gemini around the 20th or 21st, depending on the year. That makes the dates around the changeover genuine cusp days, where the sign can only be settled from the birth year and time.

The Taurus half of May is the sign in its settled and seasoned stretch: the Mercury-ruled second decan gives practical sense and a taste for craft, and the Saturn-ruled third decan adds patience, structure and long plans. The last ten days switch to early Gemini, where Mercury rules both sign and decan, and the pace quickens: more talk, more questions, more errands at once and a lighter grip on routine.

Decans here follow the triplicity system: each sign’s first ten degrees belong to the sign itself, the next ten to the next sign of the same element, the last ten to the third. Each decan’s sub-ruler is that sign’s ruling planet. Calculated by Lunonis from the same ephemeris code as our charts (astronomy-engine, checked against Swiss Ephemeris): geocentric, tropical zodiac, true equinox of date. Times are UTC: add or subtract your time zone’s offset, which can move the change to the day before or after.
