Frequently Asked Questions
What is Mercury retrograde?
A few times a year Mercury appears to move backward across the sky (an optical illusion as Earth overtakes it). Astrologically it is a time to slow down, review and double-check communication, travel and technology.
Are these dates in my time zone?
Dates are computed in UTC. A moon phase or eclipse may fall on the adjacent day in your local time zone.
