Frequently asked questions about the free calculators
Are the Circle calculators really free?
Yes. The Circle calculators are free to use and require no registration for the first reading.
How do I find my Maya sign?
Open the Maya calculator and enter your birth date. It calculates your Tzolk’in day, your position in the Haab’ and other Maya calendar markers.
How do I find my Celtic tree?
The Celtic calculator uses your birth date for the modern 21-tree reading while keeping it distinct from the Coligny calendar and Graves/Ogham reading.
How do I find my birth rune?
The Viking calculator links your birth date to a rune and a personalized Nordic reading.
What does the Inca calculator calculate?
It uses your birth date to calculate your solar gate and Moon phase, then adds modern associations with an Andean dark-cloud constellation and a Tawantinsuyu suyu, clearly separated from documented historical elements.
Do I need my exact birth time?
It depends on the calculator. The rising sign requires an accurate birth time and place; other tools can work from the date alone or provide an estimate.
What is the difference between history and modern interpretation?
ORACLASTRA identifies what comes from historical sources or documented reconstructions and what belongs to modern traditions or contemporary symbolic interpretation.
