Cusp Dates
The first and last day of every sign is a boundary day: the instant the Sun changes signs does not land on the same minute each year, and a birth time can move it to the neighbouring sign. On boundary days this tool names both possibilities; the definitive answer lives in a chart calculated with birth time and place.
Frequently Asked Questions
How are zodiac signs determined by date?
Your Sun sign is the sign the Sun occupied in the tropical zodiac on your birth date. Each sign spans roughly one month; for example, anyone born between March 21 and April 19 is an Aries.
What sign is January 1?
People born on January 1 are Capricorn. Capricorn runs from December 22 to January 19 and is the only sign that wraps around the new year.
I was born on the boundary between two signs — which one am I?
On cusp days the exact moment the Sun changes signs shifts by up to a day depending on the year and your birth time. The definitive answer comes from a birth chart calculated with your date, time and place; on boundary days this tool names both possibilities.
Do I need my birth time to find my zodiac sign?
For most dates the day and month are enough for your Sun sign. Birth time matters for the rising sign and Moon sign — and on cusp days it settles the Sun sign too.
Is the Sun sign the same as the rising sign?
No. The Sun sign comes from your birth date; the rising sign comes from your birth time and place. Daily horoscopes are usually written for Sun signs, while the rising sign describes the chart's outward doorway.
