Mercury Retrograde Dates
Calculate Mercury’s retrograde intervals for a selected year from its apparent geocentric longitude. See station times in India time, with an explanation of apparent backwards motion.
Choose a year
Navigate the turns of the year.

Enter or choose your inputs
Check dates, time zones and spelling before calculating.
Explore the result
Start with the summary, then open the details and calculation.
Keep the context
Read the method and follow a guide for more understanding.
The tool samples apparent geocentric ecliptic longitude and brackets changes in its daily angular speed. A bisection search locates each station. These are astronomical intervals, not evidence that events on Earth must go wrong.
What you get
- Retrograde starts and ends for your selected year
- Direct or retrograde status
- Calculated station times, not a random calendar
Good questions
Does Mercury actually reverse its orbit?
No. Retrograde is apparent motion as seen from Earth while both planets move around the Sun.
Should I postpone important decisions?
Do not let a transit calendar replace practical evidence. Review details when useful, but make decisions on their actual circumstances.
Do my details leave my browser?
No calculator input is sent to a server. Saved Kundlis are kept on your device only when you choose to save them.
Is the result professional advice?
No. Read the method and limitations. Interpretive material is for reflection and cultural interest, not medical, legal or financial advice.
