तस्यापि द्विशती संध्या संध्यांशश्ष तथाविध: । द्वापरका मान दो हजार दिव्य वर्ष है तथा उतने ही सौ दिव्य वर्ष उसकी संध्या और संध्यांशके हैं (अत: सब मिलकर चौबीस सौ दिव्य वर्ष द्वापरके हैं)

तस्यापि द्विशती संध्या संध्यांशश्च तथाविधः । द्वापरं द्विसहस्रं तु दिव्यवर्षाणि कीर्तितम् । संध्यासंध्यांशयोश्चैव द्विशतं द्विशतं स्मृतम् । एवं चतुर्विंशतिशतं दिव्यवर्षाणि भवन्ति ॥

Educational Q&A
The verse teaches a structured view of cosmic time: each yuga has transitional periods (sandhyā and sandhyāṁśa) that frame its main duration, emphasizing that moral and cosmic orders change gradually rather than abruptly.
Vaiśampāyana is explaining yuga-chronology, specifying the length of Dvāpara-yuga along with its beginning and ending twilight intervals, as part of a broader account of time-cycles and the waxing and waning of dharma.
