Worked example
A birth date of 15 April falls in the Aries date range (21 March to 19 April), so the chart summary is Aries, Fire, Cardinal.
What this tool does not do / Limits
Entertainment only: this tool uses a date table shown on the page. It does not predict the future, reveal personality truths, or claim astrological accuracy. It works from the birth date only and ignores birth time and birthplace, so any sign it shows is a rough date-only approximation. A full birth chart normally also needs birth time and birthplace for the moon, rising sign and house positions; none of those are computed here.
Frequently asked questions
Is this a full birth chart?
No. It is a sun-sign summary from the birth date only. Moon, rising and house positions need birth time and place.
Where do the date ranges come from?
The standard sun-sign date ranges are shown in the result logic: Aries runs 21 March to 19 April, and so on through the twelve signs.
