Sidereal calendar 2027: sign changes, retrogrades and eclipses
The slow-planet sign changes, retrograde periods and eclipses of 2027, with times in Indian Standard Time and UTC. Lahiri ayanāṁśa, mean node, true planet positions.
Calculated by Trikona's engine from JPL's DE440 ephemeris. Times are rounded to the nearest minute. This page lists calculations only; it does not interpret them.
Times on this page are checked against Swiss Ephemeris each time the calendar is generated.

Jupiter, Saturn, Rahu and Ketu: sign changes
Signs on 1 January 2027:
- Jupiter: Leo
- Saturn: Pisces
- Rahu: Capricorn
- Ketu: Cancer
| Planet | Change | India (IST) | UTC |
|---|---|---|---|
| Jupiter | Leo → Cancer (retrograde) | 25 Jan 2027, 00:55 IST | 24 Jan 2027, 19:25 UTC |
| Saturn | Pisces → Aries | 3 Jun 2027, 04:05 IST | 2 Jun 2027, 22:35 UTC |
| Jupiter | Cancer → Leo | 26 Jun 2027, 04:29 IST | 25 Jun 2027, 22:59 UTC |
| Saturn | Aries → Pisces (retrograde) | 20 Oct 2027, 06:03 IST | 20 Oct 2027, 00:33 UTC |
| Jupiter | Leo → Virgo | 26 Nov 2027, 17:58 IST | 26 Nov 2027, 12:28 UTC |
Rahu and Ketu do not change sign in 2027: Rahu stays in Capricorn; Ketu stays in Cancer all year.
Rahu and Ketu are the mean lunar nodes. The true node can sit up to about 1.8° away, so with the true node their sign-change dates differ.
With apparent positions instead (light-time and aberration included, as many astronomy programs do), the Jupiter and Saturn sign changes above move by 37 to 83 minutes.
Retrograde periods
From the station where the planet turns retrograde to the station where it turns direct. A period that starts in 2026 or ends in 2028 is listed when part of it falls in 2027.
| Planet | Turns retrograde | Turns direct |
|---|---|---|
| Jupiter | 13 Dec 2026, 05:21 IST 12 Dec 2026, 23:51 UTC in Leo | 13 Apr 2027, 07:32 IST 13 Apr 2027, 02:02 UTC in Cancer |
| Mars | 10 Jan 2027, 18:17 IST 10 Jan 2027, 12:47 UTC in Leo | 1 Apr 2027, 19:35 IST 1 Apr 2027, 14:05 UTC in Cancer |
| Mercury | 9 Feb 2027, 23:00 IST 9 Feb 2027, 17:30 UTC in Aquarius | 3 Mar 2027, 17:57 IST 3 Mar 2027, 12:27 UTC in Capricorn |
| Mercury | 10 Jun 2027, 23:40 IST 10 Jun 2027, 18:10 UTC in Gemini | 5 Jul 2027, 01:05 IST 4 Jul 2027, 19:35 UTC in Gemini |
| Saturn | 9 Aug 2027, 21:40 IST 9 Aug 2027, 16:10 UTC in Aries | 24 Dec 2027, 07:50 IST 24 Dec 2027, 02:20 UTC in Pisces |
| Mercury | 7 Oct 2027, 20:00 IST 7 Oct 2027, 14:30 UTC in Libra | 28 Oct 2027, 19:34 IST 28 Oct 2027, 14:04 UTC in Virgo |
Venus has no retrograde period in 2027.
Planets move slowly near a station, so a small difference in position moves the station time a lot. These times use true positions; programs that use apparent positions place Mercury and Mars stations about 5 to 7 minutes later, Jupiter's about 40 minutes later and Saturn's about 74 minutes later.
Eclipses
Time of greatest eclipse for the whole Earth, and the sidereal sign of the Sun (solar) or Moon (lunar) at that moment. Whether an eclipse is visible depends on where you are.
| Eclipse | Sign | India (IST) | UTC |
|---|---|---|---|
| Annular solar eclipse | Capricorn | 6 Feb 2027, 21:30 IST | 6 Feb 2027, 16:00 UTC |
| Penumbral lunar eclipse | Leo | 21 Feb 2027, 04:43 IST | 20 Feb 2027, 23:13 UTC |
| Penumbral lunar eclipse | Capricorn | 18 Jul 2027, 21:33 IST | 18 Jul 2027, 16:03 UTC |
| Total solar eclipse | Cancer | 2 Aug 2027, 15:37 IST | 2 Aug 2027, 10:07 UTC |
| Penumbral lunar eclipse | Capricorn | 17 Aug 2027, 12:44 IST | 17 Aug 2027, 07:14 UTC |
Penumbral lunar eclipses are faint, and many pañcāṅgas do not list them.

Which zodiac and settings does this calendar use?
The sidereal zodiac with the Lahiri ayanāṁśa, the mean lunar node for Rahu and Ketu, and true (geometric) planet positions. These are Trikona's default chart settings.
Why might another program show a different time?
Programs differ in ayanāṁśa, in mean or true node, and in whether they use apparent or true planet positions. For a slow planet a tiny difference in longitude moves a sign change by minutes or hours. The note under the sign-change table gives the size of the apparent-position difference for 2027.
How were the times calculated?
By Trikona's engine, from JPL's DE440 ephemeris, with the settings above. Times are rounded to the nearest minute.
Does this page say what the transits mean?
No. It lists calculated events only. Interpretation depends on the chart, the tradition and the astrologer.
