3rd decan of Taurus: Saturn
Each sign is divided into three decans, 10° slices that the Sun crosses in about ten days each. May 13 falls in the third decan of Taurus (about May 10–20), which the traditional Chaldean system assigns to Saturn. Astrologers say that adds discipline, patience and a serious streak.
Saturn brings structure and a long view. People from this decan often mature early and are willing to work slowly toward something that lasts.
The number 13 in numerology
The 13 is widely considered unlucky in Western folklore, but numerologists generally read it differently: it reduces to 4, and is linked with hard work, transformation and rebuilding from scratch.
Numerology is a separate tradition from astrology and is offered here for interest.
May birthstone and flower
The modern birthstone for May is Emerald and the commonly listed birth flower is the lily of the valley. May falls in late spring in the north and late autumn in the south.
Taurus love and compatibility
Taurus falls in love slowly and stays in love for a long time. Romance is expressed through the senses and through actions: cooking a favourite meal, remembering small preferences, creating a home that feels safe.

What zodiac sign is May 13?
May 13 falls in Taurus, which runs from April 20 to May 20 in the tropical zodiac. The Sun changes sign at a slightly different moment each year, so the boundary can fall a day or so either side of these dates. If you were born close to the edge, your birth year, time and place decide it.
Is May 13 a cusp birthday?
Not by the usual definition, which counts the first and last couple of days of a sign. May 13 is day 24 of Taurus season, so it is normally read as a clear Taurus birthday.
Which decan is May 13?
May 13 is in the third decan of Taurus (May 10–20). In the traditional Chaldean system this decan is ruled by Saturn, which astrologers say adds its own flavour to Taurus. Some modern astrologers assign decan rulers by element instead, which gives different planets, and decans are strictly 10° slices of the zodiac, so the date range is approximate.
What are the birthstone and flower for May?
The modern birthstone for May is Emerald and the birth flower is the lily of the valley. These come from calendar tradition rather than astrology, and the lists vary by country and source.
