O! TL;DR reference
Mercury retrograde in 2026
tl;dr
- Mercury appears to reverse direction three times in 2026: late Feb–Mar, late Jun–Jul, and Oct–Nov.
- Retrograde is an optical illusion — Mercury never stops; Earth simply overtakes it on a faster inner-track orbit.
- Dates below are the station instants in UTC; the apparent reversal spans a few weeks each time.
2026 Mercury retrograde periods (UTC)
| # | Stations retrograde | Stations direct | Approx. duration | Sign(s) |
|---|---|---|---|---|
| 1 | Feb 26, 2026 | Mar 20, 2026 | ~22 days | Pisces → Aquarius |
| 2 | Jun 29, 2026 | Jul 23, 2026 | ~24 days | Cancer → late Cancer |
| 3 | Oct 24, 2026 | Nov 13, 2026 | ~20 days | Scorpio → late Libra |
What 'retrograde' actually is
Retrograde motion is apparent, not real. From Earth we see Mercury trace a path against the background stars; for most of the year that path moves eastward (direct). Three times a year, as faster-orbiting Earth and Mercury line up, Mercury appears to slow, stop ('station'), drift westward for a few weeks, stop again, then resume.
Mercury never changes its actual direction of travel. The reversal is a line-of-sight effect of two bodies moving at different speeds — the same illusion you get passing a slower car on the highway.
Mercury retrogrades more often than any planet (three to four times a year) because it is the fastest, completing an orbit every 88 days and being overtaken frequently.
How these dates were produced
- Computed with the astronomy-engine library (VSOP87 planetary theory), the same engine behind astro.otldr.com.
- A station is the moment Mercury's apparent ecliptic longitude velocity crosses zero; times are rounded to the day in UTC.
- Local civil dates can differ by one day depending on time zone — convert from the UTC instant for your region.
