Mercury retrograde, 2020–2036
Every Mercury retrograde window from 2020 through 2036 — the exact instant each station occurs (UTC), the sidereal sign it happens in (Lahiri ayanāṁśa, the reckoning used in Jyotiṣa), and how long it lasts. Sidereal signs sit ~24° behind Western tropical signs, so these sign placements will differ from tropical tables — the dates and times are identical.

Common questions
How long does Mercury retrograde last?
In this table the windows run from 20 to 24 days, averaging about 22 days.
Why do these signs differ from Western retrograde tables?
The signs here are sidereal (Lahiri ayanāṁśa), the reckoning used in Jyotiṣa — about 24° behind the tropical zodiac Western sites use. The station dates and times are identical; only the sign labels shift.
How are these times computed?
Each station is the instant the planet's apparent speed crosses zero, root-found from Swiss Ephemeris positions. The method is stated below the table, so every value is reproducible — computed, not copied from an almanac.
