Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
विश्वघ्नलंबनकलाढ्योनस्तु तिथिवद्यगुः । शरोनोलंबनषडघ्ने तल्लवाढ्योनवित्रिभात् ॥ १६१ ॥
viśvaghnalaṃbanakalāḍhyonastu tithivadyaguḥ | śaronolaṃbanaṣaḍaghne tallavāḍhyonavitribhāt || 161 ||
ଶେଷରେ କଳା ଯୋଗ କରି ଲମ୍ବନ ଦ୍ୱାରା ସଂଶୋଧନ କଲେ ତିଥିର ମାନ ମିଳେ। ଶେଷକୁ ‘ଷଡଘ୍ନ’ (ଛଅଗୁଣ) କରି, ଲମ୍ବନରେ ଶୁଦ୍ଧ କରି, ସମ୍ବନ୍ଧିତ ଲବ ଯୋଗ କଲେ ଫଳ ତ୍ରିଭାଗ-ନିୟମରୁ ଭ୍ରଷ୍ଟ ହୁଏ ନାହିଁ।

It emphasizes that dharma-based observances depend on correct sacred time (kāla); accurate tithi computation safeguards the purity of vrata, pūjā, and meritorious acts.
By ensuring the correct tithi and subdivisions of time, a devotee performs worship and vows at their proper moments, aligning bhakti-practice with scriptural timing (śāstra-kāla).
Jyotiṣa Vedāṅga: it references computational steps using units like kalā and lava and corrections like laṃbana to determine tithi accurately for ritual scheduling.
