What is my zodiac sign?
Pick your birthday below and the calculator names your sun sign instantly. It does not look the answer up in a table: it computes where the Sun actually stood on your birth date, so the tricky boundary days come out right.

The ranges are the familiar reference values. The real boundary moves by about a day from year to year, which is exactly why the calculator computes instead of guessing.
§ 01
How zodiac sign dates actually work
Seen from Earth, the Sun travels through all twelve zodiac signs once a year, spending about a month in each. Your sun sign is simply the sign the Sun occupied on the day you were born.
The Sun does not respect the calendar, though. It crosses from one sign into the next at a precise moment that lands on a slightly different date each year, sometimes March 20, sometimes March 21. That is why two people born on the same date in different years can carry different signs.
§ 02
Born on a cusp?
If your birthday sits near a boundary, printed date tables will fail you: they cannot know which side of the crossing your birth fell on. The only honest answer comes from computing the Sun's position for your actual birth date, which is what this tool does.
On a true cusp day even the hour matters. The Sun can change signs at lunchtime, putting a morning baby and an evening baby in different signs. Your full birth chart, computed to the minute, removes the doubt.
§ 03
Your sun sign is just the beginning
The sun sign is one line of a much longer letter. Your Moon describes how you feel, your rising sign how you enter a room, and the houses and aspects tie it all together into something that is yours alone.
NovaOracles computes that full picture from real astronomy, personal to the minute and place you were born, and reads it for you every day.
