Frequently Asked Questions

What is a cusp date?

A date when the Sun moves from one sign to the next — around the 19th to 23rd of each month. On those dates your sign depends on the exact year and time of birth.

Can I really be a different sign than I thought?

If you were born on a boundary date, yes — the Sun's actual position at your birth hour decides it, and it varies year to year.
