Common questions
Are these astrology tools free?
Yes. Every tool here is free, needs no account and asks for no email address. Nothing you enter is stored.
Which tools update on their own?
The current planet, event calendar, Moon phase and zodiac season pages recalculate from the current time. Calculators respond to the details you enter.
Do I need my birth time?
Only for a complete birth chart, rising sign and houses. The Sun sign and Chinese zodiac calculators need a date, while sky trackers need no birth details.
