Astronomical knowledge was necessary since early Rig vedic times for the day-today-life of the people seasons for sowing, rains for growth and reaping were all acquired. Direct connection of astronomy, particularly the lunar transits, are seen in the performance of monthly rites such as Darsapurnamasa and seasonal rites such as chaturmasya. Thus vedic people had knowledge required for their religious activities. The Vedic astronomers evolved a system of five years yuga. As seen in Rigveda time period of yuga was mentioned <blockquote>दीर्घतमा मामतेयो जुजुर्वान् दशमे युगे । dīrghatamā māmateyo jujurvān daśame yuge । (Rig Veda 1.158.6)<ref>Rig Veda ([http://vedicheritage.gov.in/samhitas/rigveda/shakala-samhita/rigveda-shakala-samhitas-mandal-01-sukta-158/ Mandala 1 Sukta 158])</ref></blockquote>Prof K. S. Shukla explains the evolution of the Vedic concept of a Yuga as follows:<blockquote>''The year of vedic astronomy seems to have been a tropical one. The months were lunar and measured from full moon to full moon and also from new moon to new moon. There is evidence to show that to make the lunar year correspond to the solar year 12 days were intercalated after every lunar  year and one month was dropped after every 40 years. At a later stage, this correspondence was established by evolving a cycle of five solar years with 62 lunar months. This cycle was called a yuga.''<ref>K. S.

Yuga (युगम्) is one of the four large periods into which the basic Chaturyuga cycle is divided, it forms the basic Indian cycle of creation and destruction. Yuga Pramana is calculated in terms of Human varshas and Divya varshas. Bhagavata Purana describes the concept of time and yugas (in Divya varshas) in the following verses<blockquote>कृतं त्रेता द्वापरं च कलिश्चेति चतुर्युगम् । दिव्यैर्द्वादशभिर्वर्षैः सावधानं निरूपितम् ॥ १८ ॥ (Bhag. Pura. 3.11.18) kr̥taṁ tretā dvāparaṁ ca kaliśceti caturyugam । divyairdvādaśabhirvarṣaiḥ sāvadhānaṁ nirūpitam ॥ 18 ॥ (Bhag. Pura. 3.11.18)</blockquote><blockquote>चत्वारि त्रीणि द्वे चैकं कृतादिषु यथाक्रमम् । सङ्ख्यातानि सहस्राणि द्विगुणानि शतानि च ॥ १९ ॥ (Bhag. Pura. 3.11.19) <ref name=":3">Bhagavata Purana ([https://sa.wikisource.org/wiki/%E0%A4%B6%E0%A5%8D%E0%A4%B0%E0%A5%80%E0%A4%AE%E0%A4%A6%E0%A5%8D%E0%A4%AD%E0%A4%BE%E0%A4%97%E0%A4%B5%E0%A4%A4%E0%A4%AA%E0%A5%81%E0%A4%B0%E0%A4%BE%E0%A4%A3%E0%A4%AE%E0%A5%8D/%E0%A4%B8%E0%A5%8D%E0%A4%95%E0%A4%A8%E0%A5%8D%E0%A4%A7%E0%A4%83_%E0%A5%A9/%E0%A4%85%E0%A4%A7%E0%A5%8D%E0%A4%AF%E0%A4%BE%E0%A4%AF%E0%A4%83_%E0%A5%A7%E0%A5%A7 Skanda 3 Adhyaya 11])</ref></blockquote><blockquote>catvāri trīṇi dvē caikaṁ kr̥tādiṣu yathākramam । saṅkhyātāni sahasrāṇi dviguṇāni śatāni ca ॥ 19 ॥ (Bhag.
