Frequently Asked Questions
What dates are used for each zodiac sign?
This tool uses the standard tropical Western zodiac date ranges, for example Aries runs March 21 to April 19 and Leo runs July 23 to August 22. These are the conventional date ranges used by most Western horoscopes and calendars.
Why do some sources give slightly different date ranges?
The exact boundary date between two signs can shift by a day depending on the source, since it depends on the precise time of the sun's position each year. If your birthday falls right on a boundary date, different sources may occasionally disagree by one day.
Is this the same as the Chinese zodiac?
No — the Western zodiac is based on the sun's position on your exact birth date and has 12 signs tied to specific date ranges within a year. The Chinese zodiac instead assigns one of 12 animals to your entire birth year, which is a completely different system.
Is my birth date sent anywhere when I use this?
No — the date lookup happens entirely in your browser using JavaScript, so nothing you enter is ever sent to a server.
