Frequently Asked Questions
When Mercury retrograde in 2025?
15.03 – 07.04; 18.07 – 11.08; 09.11 – 29.11 – Eastern Time, to the minute.
What to watch for during Mercury retrograde?
Better to leave yourself margin for what comes next: signing anything important without reading it: re-read even familiar wording; buying electronics you cannot return; assuming your message arrives and lands correctly the first time; planning travel with no slack in the schedule.
What is the shadow period?
A planet first covers a stretch of zodiac going forward, then comes back over it, then crosses it a third time. The first and third passes are the shadow. The theme starts showing during the shadow and finishes after it.
Why is the date a day off on another site?
A station happens at a specific minute. If that minute falls at night, it can already be the next day in Eastern Time while in UT it is still the day before. We show Eastern Time, and the calendar tables have a time zone switch.
The wheel uses the tropical zodiac, 0° Aries on the left, signs running counterclockwise. The lines in the middle are the exact angles between planets at that moment.
