FAQ
Questions Sun Sign Calculator owners ask.
- 01
Why do I need to provide my birth year?
Zodiac sign transitions (cusps) do not occur on the same calendar day every year due to Earth's orbital variations. Providing the year ensures the calculate_cusp capability identifies the precise boundaries for your specific birth period.
- 02
What information can I get about a zodiac sign?
By using get_sign_details, you can retrieve the fundamental astrological attributes of any sign, including its element (e.g., Fire, Water), modality (e.g., Cardinal, Fixed), and polarity (e.g., Masculine, Feminine).
- 03
Can this capability calculate my full astrological profile?
Yes, by combining the calculate_cusp and get_sign_details capabilities, you can determine your sign's boundaries and its corresponding elemental and modal characteristics for a complete identity summary.
