Component 1

Udaya Lagna – Calculate the Jamakkol Ascendant

Udaya, also known as Jamakkol Lagna, is the foundation of the Jamakkol workspace. MKundali calculates its position using the birth time, the Sun’s longitude and the duration of daytime or nighttime.

How It Is Calculated

Obtain the Sun’s longitude.
Identify sunrise and sunset from Panchanga.
Calculate Dinamana (day duration).
Calculate Ratrimana (night duration).
Identify whether the birth moment falls during daytime or nighttime.
Determine the elapsed time from the applicable sunrise or sunset boundary.
Calculate the Udaya longitude from the elapsed time, the day or night duration and the Sun’s longitude.

Udaya is not the ordinary natal Lagna. If Panchanga sunrise or sunset is unavailable, the engine uses a 06:00 and 18:00 fallback. That fallback is not the Jama Graha 6-to-6 option.

Udaya Information

Udaya and the Houses

Jamakkol houses are counted from the Udaya Lagna, so the Jamakkol charts, the Planetary Positions table and the Analysis rows use houses from Udaya.

The 6-to-6 option described under Jama Grahas affects the Jama Grahas only. It does not change Udaya.

Component 2

Jama Grahas – Eight Outer Planetary Positions

MKundali calculates eight Jama Graha positions using the elapsed portion of daytime or nighttime and a weekday-dependent planetary sequence.

The Eight Jama Grahas

Sun
Moon
Mars
Mercury
Jupiter
Venus
Saturn
Snake

Snake is a Jama Graha in its own right. It is not a Rahu or Ketu position, and it is excluded from the exchange calculations.

Eightfold Day or Night Division

Daytime and nighttime are divided into eight equal periods. The applicable Jama period is determined from the selected birth moment.

Active Jama number
Jama duration
Engine Graha
Elapsed time within the active Jama
Engine longitude
Day or Night
Vedic weekday

MKundali determines the starting Engine Graha from the Vedic weekday. The other seven Jama Grahas follow the corresponding sequence, each 45 degrees from the previous position.

Actual Sunrise–Sunset or 6-to-6 Mode

The actual SR/SS mode uses the sunrise and sunset boundaries. The optional 6-to-6 mode uses a fixed 06:00 to 18:00 daytime framework. Changing the mode recalculates the Jama Graha positions.

This setting affects the Jama Graha calculation. It does not replace the separate Udaya sunrise and sunset calculation. The workspace opens with 6-to-6 mode switched on.

Component 4

Jamakkol Entities

The Jamakkol Entities table lists the Jamakkol points and the Upagrahas with their sign, degree, Nakshatra, Pada and KP lords.

Entities	Meaning
Ud	Udaya (JK Lagna)
Ar	Aarudha
Kv	Kavippu (JK)
SR	Sookshma Rashi Point
Ud7, Ar7, Al7, Sr7	The seventh-point companions of Udaya, Aarudha, the Aarudha lord point and SR
Mn, Rk, Ym, Mr	Mandi, Rahu Kala, Yamaghanta and Mrityu

Upagrahas

The four Upagrahas come from the shared Traditional Upagraha engine, the same one used by the Prashna workspace. Rahu Kala here is the Ardha Prahara.

KP lords are extra positional details for each entity.

Seventh-Point Companions

The seventh points are shown in the Entities table and in the Arc Distance Matrix. They are not drawn as chart markers.

Component 5

Aarudha, Kavippu and Sookshma Rashi Point

Three derived points sit between the Udaya and the Jama Grahas. MKundali calculates each of them from the query moment.

Aarudha

MKundali calculates a time-derived Aarudha point using the birth-time minute and second information. It is a Jamakkol point, not a general Jaimini Arudha Pada.

Kavippu JK

Calculate Kavippu using the Sun-sign-based Veethi assignment, Aarudha and Udaya sign. Jamakkol Kavippu uses Udaya as the reference Lagna rather than the ordinary birth Lagna used by the shared Prashna Chhatra approach.

Sookshma Rashi Point

MKundali calculates a Sookshma Rashi Point using the Aarudha sign, its lord’s corresponding Jama Graha position and the Udaya sign.

Aarudha Lord
Jama position of the Aarudha Lord
Udaya-to-ArL count
SR sign and degree
Nakshatra and Pada
KP planetary divisions

Cyclic Direction

On the cyclic compound-degree string used by the Analysis section, the Jama Grahas and Kavippu move backward, and the other points move forward.

MKundali Jamakkol Aarudha, Kavippu and Sookshma Rashi Point — Aarudha, Kavippu and Sookshma Rashi Point.

Component 6

Analysis and Exchanges

The Analysis section sits below the charts. It lays out the cyclic string, the positions and approaches, three kinds of exchange and the transit crossings.

Cyclic String

All the points are ordered by compound degree into one string. Jama Grahas and Kavippu are marked as moving backward; the others move forward.

Positions and Approaches

Planet → Udaya
Udaya Lord Jama in Bhava
Aarudha Bhava
Udaya → Aarudha distance
Planet → Arudha
Kavippu Bhava and Kavippu → Planet
Active Hora
Mandi Bhava
Planet → Mandi, Rahukala, Yamaghanta, Mrityu
Planet → SR

Houses 6, 8 and 12 are flagged for some rows, and houses 3 and 11 are marked favourable for the Udaya to Aarudha distance.

Three Exchanges

IInner–Inner (Parivartana)
OInner ↔ Outer
JJama ↔ Jama

Each type is listed separately. Snake is excluded from the exchanges.

Transit Crossings

Sun → Kavippu
Moon → Kavippu
Sun → SR
Moon → SR
Aarudha → SR

These are estimates. The Sun and Moon crossings use fixed average daily speeds, and the Aarudha to SR time uses a fixed 6° per minute. They are not exact crossing times.

Component 7

Bhava Positions and Varga Bhava Positions

Two tables show the Bhava cusps measured from the Udaya Lagna, one for the main chart and one for a chosen divisional chart.

Bhava Positions

Equal house system (default)
Placidus
Sripati
Ascendant at the middle of the 1st house (default)
Ascendant at the start of the 1st house

The selection also updates the cusp markers on the Jamakkol charts.

Varga Bhava Positions

Choose a divisional chart from D2 through D144 and view the Bhava positions for it, with the same ascendant option. D9 is selected first.

Varga Bhava is a Jamakkol table on the selected divisional chart. It is not a separate Prashna or Parashari calculation.

Component 8

Rashmis – Ray Values by Sign

The Rashmis table gives each of the twelve signs a ray value, adds the rays of the planets in it, and shows inner and outer totals.

What the Table Shows

Sign and the sign ray
Inner planets, with their adjusted rays
Inner total
Jama planets, with their adjusted rays
Outer total
Combined Total column, when Show Total is on

The sign ray is counted once, in the inner total.

Ray Adjustments

Exaltation multiplier
Debilitation multiplier
Combustion multiplier
Retrograde multiplier

Combustion and retrograde apply to the inner planets only. The multipliers are shown beneath the table.

Preferences and Show Total

The ray values and the multipliers come from the existing Rashmi preferences in MKundali. Show Total Rashmis is a switch in the Options flyout.

Rashmis are a Jamakkol ray table. They are not Shadbala.

Component 9

Varsha Vimsottari

The Jamakkol workspace includes a Varsha Vimsottari browser, derived from the Mudda Dasa used for the annual cycle.

How It Works

The chart Moon sets the Dasha sequence, and the sequence runs from the chart moment, compressed into one Varsha year. It reuses the Mudda Dasa browser component that serves the annual Dasha views.

Year-Length Options

Savana Year, 360 days (default)
Mean Sidereal Solar Year
Mean Tropical Solar Year
True Tropical Solar Year
True Sidereal Solar Year
Year with 360 Tithis
User-Defined Year

Find Dasha

Enter a date and time and use Find to open the Dasha running at that moment. The Varsha year is counted from the chart date, and the browser shows the chain of periods for the selected date.

This is the Varsha Vimsottari browser only. It is not a separate full Dasha system.

Component 10

Arc Distance Matrix

The Arc Distance Matrix measures the arc from each row entity to each column entity and prints it in degrees, minutes and seconds.

Rows and Columns

Rows: the nine inner planets, Udaya, Aarudha and the Jama Grahas
Columns: those same entities
Columns also include Ud7, Ar7, Arl7, SR, Sr7, Kv and the four Upagrahas

Direction
