Saturday is regarded as Shani Dev's (Shanaishchar's) day — because Shani presides over the first hora of that day. At the same time, in Maharashtra, Saturday is also regarded as Maruti's (Hanuman's) day — a fact recorded independently by the state's official Marathi encyclopaedia. By one popular legend, Hanuman once rescued or overpowered Shani from trouble, and a grateful Shani promised protection to Hanuman's devotees from the hardship of sade-sati — which is why Shani and Maruti are worshipped together on Saturdays. This vrat isn't bound to a tithi or a masa — it applies on every Saturday of the year (52 Saturdays in all in 2026).
⚠️ Looking for Shani Jayanti, Shani Amavasya, or Shravani Shanivar? Those are three calendar-specific sibling pages, each falling only a handful of times a year — Shani Jayanti and Shani Amavasya are tithi-based, while Shravani Shanivar follows a masa-plus-weekday rule (the Saturdays that fall within Shravan). This page covers every Saturday of the year in general. The difference is set out in the Regional customs section below.
Shani is the slowest-moving of the nine grahas — believed to reward honesty, discipline, and hard work, and to teach a lesson to injustice and arrogance. The Marathi encyclopaedia records that Saturday gets its name because Shani presides over the first hora of that day.
In Maharashtra, this same Saturday is also given equally important worship dedicated to Maruti (Hanuman) — the claim that "Saturday is Maruti's day" is recorded independently across three separate sources (the state's official Marathi encyclopaedia and two independent Marathi news sources), which makes it a well-corroborated claim. By Maharashtrian popular belief, Hanuman is regarded as a deity capable of exerting influence over Shani himself, protecting devotees from Shani's afflictions — so worship of Maruti on Saturday is considered just as important as (in some households, even more important than) worship of Shani.
In astrology, Shani's sade-sati (roughly seven and a half years, counted from the moon sign) and dhaiya (two and a half years) are regarded as difficult periods; there's a widespread belief that Saturday worship eases this hardship — this is an astrological claim, not a scientific guarantee.
The Marathi encyclopaedia also records a general custom of an oil-massage bath (abhyangasnan) on Saturdays — this isn't limited to Shani worship specifically; it's a broader Ayurvedic and traditional health practice.
Two distinct story threads are connected to Saturday worship — they're kept separate here, not blended together.
Shani Mahatmya — the story of King Vikramaditya: the nine grahas once argued over precedence among themselves; unable to settle it, they went to Indra, who sent them to the just king Vikramaditya for a decision. The king had nine thrones made, one each of gold, silver, bronze, brass, lead, tin, zinc, mica, and iron, arranged in order of rank — Shani was given the lowest, the iron throne. Insulted, Shani grew angry and vowed to show the king his power. Taking the form of a horse-trader, he gave the king a wondrous horse, which later vanished, leaving the king stranded in a distant land. There, falsely accused of theft, the king had his hands and feet cut off as punishment, and spent the sade-sati period — roughly seven years — labouring at an oil press in hardship. Eventually, moved by one kind person's compassion, Shani's heart softened; as the sade-sati ended, the king's prosperity and limbs were restored. The moral, as it's told, is that Shani puts faith and patience through a severe test, but grants justice and grace in the end.
The Hanuman-Shani relationship — the origin of why Saturday belongs to both: three different versions of this exist — none is presented here as the single "true" one. In one version, an arrogant Shani struck Hanuman on the head; Hanuman responded by overpowering him, and the defeated Shani accepted the custom of being offered oil, cotton, and urad dal. In another version, Shani tried to trouble a meditating Hanuman, who wrapped his tail around Shani from foot to neck and dragged him all the way to Ram Setu, at which point Shani begged forgiveness. In a third version, Ravana had imprisoned Shani in Lanka (holding him responsible for Meghnad's fate); while searching for Sita, Hanuman freed the imprisoned Shani, and a grateful Shani granted him a boon. The shared core across all three: in this encounter, Hanuman gets the upper hand over Shani, Shani becomes grateful or humbled, and promises protection to Hanuman's devotees from his own ill effects — which is why worshipping Hanuman on Saturday is considered especially effective against Shani-related troubles.
"Sampat Shanivar," a separate, Shravan-limited folk story connected to the Saturdays of that month, is a different story again — it isn't retold here, and belongs to the separate Shravani Shanivar page.
General devotees of Shani and Maruti — those who worship both deities together on Saturday. Those who, by astrological belief, are going through sade-sati, dhaiya, or a Shani mahadasha, or believe Shani is weak or unfavourably placed in their horoscope, particularly observe this vrat. What exactly to do varies by tradition and belief — it isn't presented here as a universal obligation.
A researched sequence — details can vary by tradition:
Udyapan (closing ritual): once a chosen number of Saturdays is complete (sources disagree on the number — see below), the vrat is typically closed with a special puja, a havan, mantra chanting, and a meal or donation for Brahmins or those in need — this is a general pattern; no Marathi-specific detail was found.
The exact vidhi, materials, and closing details can vary by family and region — this shouldn't be taken as the one correct procedure.
(This list can vary by tradition.)
A single meal a day — whether eaten in the morning or the evening, both are accepted according to sources. A sattvic diet is expected — salt, meat, alcohol, and onion-garlic are avoided; including black sesame, urad dal, and jaggery in the diet is considered auspicious.
Sources don't agree on how many Saturdays the vrat should be observed for — some traditions specify a fixed number of Saturdays, such as eleven, twenty-one, thirty-one, or fifty-one (similar to Solah Somvar), some suggest observing it continuously for a year, and others say "until the sade-sati or dhaiya period ends." No single number is presented here as the final word.
Those who are elderly, pregnant, unwell, or on regular medication should avoid a strict fast — observe it gently, according to your health.
The Maharashtrian emphasis on Saturday also being Maruti's day is a genuinely notable feature — recorded independently by the state's official Marathi encyclopaedia and two separate Marathi news sources. Pan-Indian sources usually emphasise only the Shani side, without giving the Maruti side the same weight.
Most villages and neighbourhoods in Maharashtra have a Maruti temple; it's a general observation that these see larger-than-usual crowds for oil-and-vermilion offerings on Saturdays — no official association with any particular temple is assumed here.
In some traditions, and in much of the rest of India, Tuesday is also regarded as a major day for Hanuman — see Mangalvar Vrat (Hanuman), a separate, distinct page from this one.
| Page | Scope | Primary deity |
|---|---|---|
| This page — Shanivar Vrat | Year-round, every Saturday (52) | Shani + Maruti |
| Shani Jayanti | Once a year (tithi) | Shani (birth anniversary) |
| Shani Amavasya | Amavasya + Saturday (2-3 times a year) | Shani |
| Shravani Shanivar (Sampat Shanivar) | Only the Saturdays within Shravan | Maruti (Ashwattha puja) |
In 2026, Shani Jayanti and Shani Amavasya both fall on the same Saturday, 16 May, and another Shani Amavasya falls on Saturday, 10 October — details for both dates are on the Shani Jayanti and Shani Amavasya pages respectively, and aren't repeated here. Shani Pradosh (a Trayodashi-based coincidence) falls on a Saturday on 14 February and 27 June — details are on the Pradosh family pages. None of these dates are part of the Shanivar Vrat's own definition — this vrat applies the same way on every Saturday; they're noted here only as a useful reference for readers.
