Narada Purana — Purva Bhaga, Shloka 39
Tithi-Nirṇaya for Vratas: Ekādaśī Rules, Saṅkrānti Punya-kāla, Eclipse Observances, and Prāyaścitta
पूर्वद्वये परेद्युः स्यात्संगवात्परतो मनीषिभिः । सद्यः कालः परेद्युः स्याज्ज्ञेयमेवं तिथिक्षये ॥ ३९ ॥
pūrvadvaye paredyuḥ syātsaṃgavātparato manīṣibhiḥ | sadyaḥ kālaḥ paredyuḥ syājjñeyamevaṃ tithikṣaye || 39 ||
Apabila berlaku tithi-kṣaya (tithi lenyap), para bijaksana menyatakan bahawa dalam dua bahagian masa yang pertama, ‘hari berikutnya’ (paredyuḥ) terpakai. Namun selepas tempoh saṅgava, ‘masa hari yang sama’ hendaklah diketahui sebagai milik ‘hari berikutnya’—demikianlah difahami ketika tithi hilang.
