कालमानं मुहूर्ताङ्गानि च
जयासौम्ये गुरौ रिक्ता शनौ पूर्णेति नो शुभाः ।नन्दा तिथिः शुक्रवारे सौम्ये भद्रा कुजे जया ॥ २४४ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 244.
Jaya on Wednesday, Rikta (empty tithi) on Thursday, Purna on Saturday. These are not good. The tithi (moon day) Nanda on Friday, Bhadra (tithis 2, 7 and 12) on Wednesday, Jaya on Tuesday.
Simple meaning: Some tithi and weekday pairs are not good. Then a second set of pairs starts.
रिक्ता मंदे गुरोर्वारे पूर्णा सिद्धाह्वया अमी ।
These pairs are called Siddha. Then pairs of weekday and tithi begin: Monday on the 11th, Sunday on the 12th.
षष्ठी गुरौ तृतीया ज्ञेऽष्टमी शुक्रे शनैश्चरे ।
These weekday and tithi pairs are called burnt days.
भरण्यर्कदिने चंद्रे चित्राभौमेतु विश्वभम् ।
Six weekday and star pairs are named: Bharani, Chitra, Uttara Ashadha, Dhanishta, Uttara Phalguni and Jyeshtha.
