Muhurta Chintamani's plate (p. 8) names seven yogas made from the weekday and the tithi. Two pair the weekday with a tithi class and are favourable: Siddha and Amrita. Five pair it with a tithi number and are set aside: Krakacha, Samvartaka, Dagdha, Visha and Hutashana. The book itself records two readings of Amrita's Saturday cell. Kalaprakasika (1917, p. 206) gives the same Siddha cells and a Visha list with Tuesday and Wednesday swapped and none for Sunday or Saturday.
☕ A weekday, a tithi, and seven names
Every tithi belongs to one of five classes: Nanda, Bhadra, Jaya, Rikta and Purna. Muhurta Chintamani pairs the weekday with a class to name two favourable yogas. Siddha falls on a Jaya tithi on Tuesday, Bhadra on Wednesday, Purna on Thursday, Nanda on Friday and Rikta on Saturday, and on no tithi at all on Sunday or Monday. Amrita has a class for every weekday. On some weekdays the favourable class is Rikta, the class the books otherwise set aside: the pairing, not the class alone, is what the rule reads.
Five more yogas use the tithi's number. Krakacha (“saw”) is the 12th tithi on Sunday, the 11th on Monday, and one less each day to the 6th on Saturday; count Sunday as 1 and the weekday and the tithi always add up to 13. Samvartaka falls only on Sunday and Wednesday. Dagdha (“burnt”), Visha and Hutashana (“fire”) have one tithi for every weekday. The tradition holds these five pairs unfit for starting new work.
Two cautions. The book itself says some writers read Amrita's Saturday cell as Mrita, the opposite kind of yoga, and its commentator argues for Amrita; both readings are on its page (p. 11), and this page picks neither. And Kalaprakasika (1917, p. 206) gives a Visha list with the Tuesday and Wednesday tithis swapped and none for Sunday or Saturday, and a different Wednesday Dagdha. The two books are one tradition, so where they agree it shows the table was handed down, and where they differ the reader should know both.
Nava Panchangam does not use this rule in its day score. This page explains it as the books give it.

Frequently Asked Questions
Is this Siddha yoga the same as the Siddha yoga in the app?
No. The app's Siddha yoga pairs the weekday with the Moon's star, and it is simply every pair that is neither Amrutha nor Marana. Muhurta Chintamani's Siddha pairs the weekday with a tithi class. The names match; the rules do not.
What is contested about Saturday?
Amrita's Saturday cell. Muhurta Chintamani itself (p. 11) says some writers read that clause as Mrita, the opposite kind of yoga, while its commentator argues it is Amrita. The table marks the cell with a star and picks neither reading.
Where do Kalaprakasika and Muhurta Chintamani differ?
Kalaprakasika (p. 206) gives Siddha by class on the same five weekdays with the same classes. Its Visha list puts the 2nd tithi on Tuesday and the 7th on Wednesday, where Muhurta Chintamani has the 7th on Tuesday and the 2nd on Wednesday, and it gives no Visha for Sunday or Saturday. Its Wednesday Dagdha is the 2nd tithi, not the 3rd.
Why is Rikta favourable on some weekdays here?
Because these yogas read the pair, not the class alone. The plate pairs Rikta with Saturday for Siddha and with Thursday for Amrita. A Rikta tithi on another weekday is not one of these yogas.

✨ Siddha and Amrita: the weekday and the tithi class
From the plate (p. 8). * marks the cell the book itself records two readings of (p. 11).
| Weekday | Siddha: tithi class | Amrita: tithi class |
|---|---|---|
| Sunday | none | Nanda |
| Monday | none | Bhadra |
| Tuesday | Jaya | Nanda |
| Wednesday | Bhadra | Jaya |

| Saturday | Rikta | Purna * |
The classes are explained on the five tithi classes.
🔢 The five yogas set aside: the weekday and the tithi number
From the same plate. The number is the tithi's place in the fortnight; – means the yoga does not fall on that weekday.
