Gulika and Mandi in Kundli: Saturn’s Eighth of the Day and Night

The word Gulika turns up in two places that look unrelated. The daily panchang prints a Gulika Kaal, a stretch of the day set aside alongside Rahu Kaal and Yamaghanta. Some birth charts carry a small extra marker, labelled Gulika or Mandi, sitting in one of the signs. Both come out of the same arithmetic: the day is cut into eight parts, one part belongs to Saturn, and the chart point is the ascendant at a moment inside that part. This page works the arithmetic, checks it against the site’s own panchang for every day of two years, and shows where the traditions part ways.

Gulika (गुलिक) and Mandi (मांदि): Upagrahas, Not Grahas

Gulika and Mandi belong to the upagrahas, the “sub-planets” that Brihat Parashara Hora Shastra describes alongside the grahas. An upagraha has no body in the sky. It is a calculated point, and these two are tied to Saturn, शनि (Shani), the graha the site’s planet table lists as malefic and as karaka of “longevity, karma, labour, servants, old age, iron, coal, and delay itself”. Nothing on this page turns that signification into a reading. The aim is narrower: to say how the point is found, and why two calculators can put it in different signs.

Eight Parts of the Day, Seven Lords in Weekday Order

In the Parashari scheme the span from sunrise to sunset is divided into eight equal parts. The first part goes to the lord of the weekday, and the rest follow in the order of the weekdays themselves: Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, then round again. Seven lords cannot fill eight parts, and the scheme leaves the eighth part without a lord. The part that falls to Saturn is Gulika’s.

On a Sunday the count runs Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, so Saturn holds the 7th part. On a Saturday, Saturn is the weekday’s own lord and holds the 1st. Each day back from Saturday moves it one part later. No node appears in the sequence: the weekdays are named for the seven visible grahas only, and Rahu and Ketu have no part of the day in this scheme.

The night, from sunset to the next sunrise, is cut into eight parts the same way. The tradition opens the night’s count not on the weekday’s lord but on the lord of the fifth weekday counted from it, Sunday included: on Sunday night the count begins with Jupiter. From there it runs in weekday order as before. The table below applies both rules.

Two things follow from the table. Saturn never lands on the lordless 8th part, by day or by night. And by night Saturn’s part is always four places earlier than by day, counted round the seven: Sunday’s 7th by day becomes the 3rd by night.

Checked Against Two Years of the Panchang

The day column is not just a rule on paper. The site’s daily panchang prints a Gulika window for New Delhi on every date from 1 Jan 2026 to 31 Dec 2027, worked out from tabulated sunrise and sunset. Measuring each window against that day’s sunrise and daylight gives its part number, and on 730 of the 730 days it is exactly the part the weekday count predicts. So the Gulika Kaal of the panchang and the Saturn part of the chart calculation are the same stretch of daylight. The night column has no printed window to check against, since the panchang gives Gulika for the day only; it is the scheme’s rule applied, nothing more.

Not the Same as Saturn’s Choghadiya

The choghadiya also cuts daylight into eight and also gives Saturn a slot, Kaal. But the choghadiya walks the planets in the Chaldean order, the sequence the hora table uses, while Gulika follows the weekday order. The two orders agree on where Saturn sits only when Saturn opens the day, so Gulika Kaal coincides with the Kaal choghadiya on Saturday alone. On the other days Gulika Kaal falls on another choghadiya: Rog on Sunday, Char on Monday, Amrit on Tuesday, Shubh on Wednesday, Udveg on Thursday, Labh on Friday. The choghadiya page tabulates these meetings for Rahu Kaal and Yamaghanta as well.

Gulika and Mandi: One Point or Two?

Knowing the part is not the same as knowing the point. For the birth chart, Gulika or Mandi is the degree of the zodiac rising on the eastern horizon, the ascendant, at a chosen moment within Saturn’s part of the birth day or night. Two questions are not settled across the traditions:

• Which moment. Some practitioners take the ascendant at the start of Saturn’s part. Others take its middle, and others its end. Some astrology programs leave the choice to the user rather than settle it.
• One name or two. Some writers use Gulika and Mandi as two names for one point. Others keep them apart, computing both from Saturn’s part but at different moments within it, so that a chart can show two markers a few degrees or a sign apart.

This page does not pick a side and gives no degree rule. What it can do is measure how much the choice matters. Running the site’s ascendant routine at the start, middle and end of all 730 of New Delhi’s printed Gulika windows, the ascendant moves between 17° (on 21 Nov 2026) and 32° (on 13 Mar 2027) from the start of the part to its end. Start and end put the point in different signs on 557 of the 730 days; start and middle, on 283. Counting houses by whole signs from the lagna, as this site does, a disagreement over the moment is often a disagreement over the house.

Why the Point Moves with Sunrise and Latitude

Every part is an eighth of that day’s own daylight, not a fixed 90 minutes. In New Delhi daylight runs from 619 minutes on 17 Dec 2026 to 838 minutes on 14 Jun 2026, so a daytime part lasts from 77.4 to 104.8 minutes; night parts run from 75.3 to 102.6. The later the part, the more the drift accumulates. On a Saturday Saturn’s part begins at sunrise itself. On a Sunday it begins six parts in, and over the two years that gap ranges from 464 to 629 minutes after sunrise, a spread of 165 minutes. Since the ascendant passes through all twelve signs in a day, a shift of that size moves the rising degree a long way.

Latitude stretches or squeezes the same effect. Of the 38 cities the site keeps a panchang for, Thiruvananthapuram (latitude 8.5° N) has the smallest swing in daylight across the year, 61 minutes, and a daytime part there stays between 87 and 95 minutes. Jammu (latitude 32.7° N) has the largest, 260 minutes, and its parts run from 74 to 108 minutes. The weekday count is the same everywhere; the clock it lands on is local. That is why this page prints no time for Gulika Kaal: a single time quoted for all of India cannot be right for all of it. The daily page for your city gives the window from that city’s own sunrise.

One more trap sits at the edges of the night. A panchang day runs from sunrise to sunrise. A birth after midnight but before sunrise therefore falls in the night of the previous weekday, and the previous weekday’s night count applies. A calculator that uses the calendar date instead will start the count on the wrong lord.

Gulika in Lagna, the 8th House, the 10th: What This Page Does Not Do

Searches for Gulika in the lagna, or in the 1st, 8th, 10th or 12th house, are asking for a reading. This page gives none, for any house. The reason is the one measured above: the house Gulika or Mandi occupies depends on a convention the traditions have not agreed on, and on 557 of 730 days in New Delhi the two ends of Saturn’s part fall in different signs. A house reading published without saying which convention placed the point could be describing the wrong house. The page also says nothing about the body or health, gives no time of day for Gulika Kaal, and offers no remedy. For Saturn’s own aspects, see Shani drishti; for the rest of the daily almanac, the guide to reading today’s panchang; and for the graha itself, the Saturn page.
