What is Sade Sati: the 7.5-year Saturn cycle, mechanically
Sade Sati is the most searched Saturn term in India and the most misexplained. Strip the fear content away and what remains is a piece of deterministic astronomy: Saturn crossing three consecutive signs positioned around your natal Moon, roughly two and a half years per sign, once every 29 to 30 years. This page carries the definition done properly, the three phases, the current cycle's engine-computed dates and the live status of all twelve moon signs.
The definition, done properly
Every Vedic birth chart fixes the Moon in one of twelve sidereal signs. That sign is the rashi, the reference point for this technique. Saturn orbits the Sun in about 29.5 years, which works out to roughly two and a half years per zodiac sign. When Saturn enters the sign immediately before your natal Moon sign, the count begins. It continues while Saturn crosses your Moon sign itself and ends when Saturn leaves the sign immediately after. Three signs, three passes of about 2.5 years each, approximately 7.5 years in total. That is the whole definition. There is no hidden trigger, no priest-side determination and nothing that requires interpretation to date: given a birth chart and an ephemeris, the start and end dates are arithmetic.
The single most common reader confusion is worth settling head-on: Sade Sati keys off the Moon sign, not the sun sign. If you know yourself as "a Leo" from newspaper horoscopes, that is a tropical sun sign and it tells you nothing about your Sade Sati. It is also not the ascendant, even though the ascendant is the usual reference for house-based transit reading elsewhere on this site. Two people born the same week can be years apart in their Sade Sati timing because the Moon changes signs every two and a quarter days while the Sun takes a month. The one input you need is the sidereal Moon sign from your date, time and place of birth; the age calculation page walks through getting it and converting it into your personal cycle dates.
One more boundary worth drawing: Sade Sati is not the only Moon-referenced Saturn transit. Saturn crossing the 4th or 8th sign from the Moon is a separate, shorter convention called dhaiya or kantaka Shani, and the two get conflated constantly. The dhaiya vs Sade Sati comparison separates them.
The three phases, mechanically
The 7.5 years are not one uniform experience, and treating them as one block is the main analytical error in popular coverage. The cycle splits into three sub-periods defined by which house from the Moon Saturn occupies.
- Rising phase (Saturn in the 12th from the Moon, roughly 2.5 years). The 12th from the Moon governs expenses, losses, isolation and sub-surface processing. The classical texture is distributed friction: costs that do not resolve, decisions that keep getting postponed, commitments that stretch. Most people only identify this phase in hindsight.
- Peak phase (Saturn over the natal Moon, roughly 2.5 years). The classical janma Sade Sati. Pressure concentrates on the Moon's own themes: emotional baseline, mother, home, daily comfort. This is the stretch most people mean when they say "Sade Sati", and it is where the tradition places both the heaviest load and the most durable consolidation.
- Setting phase (Saturn in the 2nd from the Moon, roughly 2.5 years). The 2nd from the Moon governs accumulated resources, family and sustenance routines. Conventionally the lightest phase; the system has adjusted and the consolidation of the peak starts reading through as structure.
Each phase also carries a dignity modifier: Saturn transits its own sign very differently from a sign where it is debilitated, which is why the same phase name can be mild for one rashi and sharp for another. The full phase-by-phase treatment, including the dignity table and the operational reading of each sub-period, is in the three phases of Sade Sati explained; this hub deliberately stays at the summary level.
Where the current cycle stands
The dates below are engine-computed with Swiss Ephemeris under the True Pushya Paksha sidereal ayanamsa. Lahiri-based panchangas will show these ingresses days to weeks apart from ours; that is an anchor-choice difference, not an error, and the ayanamsa comparison covers it.
| Date | Event | What changes |
|---|---|---|
| 20 March 2025 | Saturn enters sidereal Pisces | Aquarius Moon enters setting phase. Pisces Moon enters peak. Aries Moon enters rising. Capricorn Moon exits Sade Sati. |
| 23 May 2027 | Saturn enters sidereal Aries (first pass) | Aquarius Moon exits Sade Sati. Pisces Moon advances to setting. Aries Moon advances to peak. Taurus Moon enters rising. |
| 4 November 2027 | Saturn retrogrades back into Pisces | The new Aries-window phases pause; the Pisces-window configuration gets a roughly 14-week encore. |
| 11 February 2028 | Saturn re-enters Aries (final) | The Aries-window phases resume and run without further interruption at the Pisces boundary. |
So as of mid 2026, with Saturn in Pisces: Aquarius Moons are in their final (setting) phase, exiting the cycle at the 23 May 2027 ingress; Pisces Moons are at peak, with Saturn sitting on the natal Moon; and Aries Moons are in the rising phase, the approach stretch before their 2027 to 2029 peak. Everyone else is outside the cycle entirely, whatever a worried relative may have said.
The 23 May 2027 ingress is the hinge that turns the whole wheel one position: Aquarius steps out, Pisces steps down to setting, Aries steps up to peak and Taurus steps into the approach. The retrograde excursion between 4 November 2027 and 11 February 2028 briefly restores the old configuration, which for Aquarius Moons reads as a short setting-phase encore before the final Aries entry closes the door. The corpus treatment of that whole window, including Saturn's Taurus ingress on 21 July 2029 and the final Pisces Moon exit on 7 April 2030, is in Sade Sati 2027 to 2030 by rashi. The market-facing and mundane reading of the same ingress sits in what happens when Saturn enters Aries.
All twelve moon signs, current status
Each rashi links to its dedicated page with the full phase-by-phase dates. Status is as of Saturn in sidereal Pisces (20 March 2025 to 23 May 2027).
| Moon sign | Current status |
|---|---|
| Aries (Mesha) | Rising phase now; the peak from 23 May 2027 is the hardest of any rashi, with Saturn debilitated. |
| Taurus (Vrishabha) | Not in the cycle; rising phase begins 23 May 2027, with an unusual sharper-early profile. |
| Gemini (Mithuna) | Not in the cycle; rising phase begins with Saturn's Taurus ingress on 21 July 2029. |
| Cancer (Karka) | Not in the cycle; the next window runs approximately 2032 to 2039. |
| Leo (Simha) | Not in the cycle; next begins around 2034, the second-hardest configuration by Saturn dignity. |
| Virgo (Kanya) | Not in the cycle; next begins around 2036, one of the most constructive configurations. |
| Libra (Tula) | Not in the cycle; next begins around 2038, the only rashi with Saturn exalted at peak. |
| Scorpio (Vrishchika) | Not in the cycle; next begins around 2040, opening with an exalted-Saturn rising phase. |
| Sagittarius (Dhanu) | Not in the cycle; the last one ended with a constructive own-sign setting phase, next runs 2043 to 2052. |
| Capricorn (Makara) | Exited 20 March 2025 after an unusually constructive own-sign cycle; next begins around 2046. |
| Aquarius (Kumbha) | Setting phase now; exits 23 May 2027, with a brief retrograde encore in late 2027. |
| Pisces (Meena) | Peak phase now; setting from 23 May 2027, final exit 7 April 2030. |
Is it actually bad?
The honest answer has three parts. First, the base-rate problem. Seven and a half years is nearly a tenth of a lifespan. Any window that long in an adult life will contain job changes, relocations, illnesses in the family and losses, whether or not Saturn is anywhere near the natal Moon. When someone inventories their Sade Sati years and finds hardship, the inventory means nothing until it is compared against the same person's non-Sade-Sati years and against what a random 7.5-year stretch contains. Almost nobody runs that comparison. The tradition asserts the correlation; it does not measure it. What a measured version of such a claim even looks like is covered in calibrated lift.
Second, the structural reading is pressure, not doom. The classical claim is specific: Saturn on or beside the Moon correlates with consolidation phases, where expansion is harder, comfort is thinner and the durable structures of a life get renegotiated. That is a materially different claim from "your marriage will break" or "you will lose money in year three", and the difference matters. Pressure windows are survivable and often retrospectively valued; scheduled catastrophe is a fear product. The severity also varies sharply by rashi because Saturn's dignity differs across the three signs of each cycle: the Capricorn and Aquarius cycles run through Saturn's own signs, while the current Aries peak has Saturn debilitated. Same technique, very different weather. The spiritual-register reading of the same period is in Saturn's Sade Sati as a lesson structure.
Third, the evidence status, stated plainly. Tempora has publicly backtested exactly one Sade Sati signature: the Aquarius Moon configuration, published with method and result in the calibrated Aquarius study. That study did not support the guaranteed-disaster framing; it found the classical fear narrative overstated for that sign. It also covers one sign out of twelve, which means the general claim remains untested here as everywhere else. We will not sell you a remedy either way. If the period worries you, the operational responses that do not involve rituals or donations are collected in practical Sade Sati responses, without rituals.
Check your own dates
You need one input: your sidereal Moon sign. Not the sun sign from a horoscope column, not the ascendant. If you have your birth date, time and place, Kaal computes the Moon sign with the same ephemeris and ayanamsa used across this cluster; any Vedic calculator will also do it, though most default to Lahiri and will place boundary dates slightly differently. With the Moon sign in hand, the age calculation page converts it into the ages and calendar years your cycles start, and how to know your Sade Sati is ending carries the exit-date math and the difference between a phase ending and the cycle ending.
Two adjacent references complete the toolkit. Saturn's transit behaviour generally, ingress dates, retrograde loops and how to read any Saturn transit against a chart, is in the Saturn transit guide. And the planet-level page collecting every Saturn cycle Tempora tracks, from Sade Sati to the 29-year return, is at Saturn cycles.
Frequently asked
Is Sade Sati calculated from the Moon sign or the sun sign?
The Moon sign, always. Sade Sati is defined as Saturn transiting the sign before your natal Moon, your natal Moon's sign and the sign after it. The sun sign used in Western horoscope columns is a different chart point in a different zodiac and gives the wrong answer. The ascendant is also not the reference for Sade Sati, although it is the reference for house-based transit reading generally. You need your sidereal Moon sign, computed from date, time and place of birth.
Which moon signs are in Sade Sati right now?
With Saturn in sidereal Pisces (under the True Pushya Paksha ayanamsa, since 20 March 2025), three moon signs carry the cycle: Aquarius Moon is in the final setting phase, Pisces Moon is at peak and Aries Moon is in the rising phase. This holds until Saturn enters Aries on 23 May 2027, when Aquarius exits, Pisces moves to setting, Aries moves to peak and Taurus enters the rising phase. Ayanamsa choice shifts these dates by days to weeks; most Lahiri-based listings will differ slightly.
How long does Sade Sati actually last?
Approximately seven and a half years: three consecutive sign transits of roughly two and a half years each. The exact length varies by a few months per cycle because Saturn's speed varies and its retrograde loops near sign boundaries add or subtract weeks. The current Aquarius Moon cycle, for example, runs about 7 years and 4 months. The cycle repeats once every 29 to 30 years, the length of Saturn's orbit.
Is Sade Sati always a bad period?
The classical reading describes structural pressure on the Moon's themes, not scheduled disaster. Any seven and a half year window in an adult life contains job changes, moves, health events and family losses at some base rate; attributing whatever happens during Sade Sati to Sade Sati, without comparing against that base rate, is the standard attribution error. The severity also varies sharply by sign because Saturn's dignity differs: Saturn transiting its own signs (Capricorn, Aquarius) reads far more constructive than Saturn debilitated in Aries. Tempora has published one calibrated backtest of a specific configuration, the Aquarius Moon cycle, and the guaranteed-disaster framing is not supported there.
When does the current Sade Sati end?
By moon sign, under True Pushya Paksha: Aquarius Moon exits on 23 May 2027 when Saturn first leaves Pisces, with a brief encore of the setting configuration during Saturn's retrograde dip back into Pisces between 4 November 2027 and 11 February 2028. Pisces Moon exits on 7 April 2030 when Saturn settles in Taurus. Aries Moon, whose peak begins 23 May 2027, runs until Saturn leaves Taurus in the early 2030s. Each sign's page carries its own exit math.
Is there evidence Sade Sati correlates with anything measurable?
Mostly untested, honestly. The transit timing itself is deterministic astronomy, but whether the window correlates with elevated rates of any event class is an empirical question that the tradition asserts rather than measures. Tempora has publicly backtested one signature, the Aquarius Moon configuration, and publishes the method and result; the broader claim across all twelve signs has not been calibrated. Tempora's dated, scored forward calls live on the Tracker, and Sade Sati pages are context rather than scoreboard entries.
