Date

None of the ancient texts mention when Chandragupta was born. Plutarch claims that he was a young man when he met Alexander III during the latter's invasion of India (c. 326 -325 BCE). Assuming the Plutarch account is true, Raychaudhuri proposed in 1923 that Chandragupta may have been born after 350 BCE. According to other Greco-Roman texts, Chandragupta attacked the Greek-Indian governors after Alexander's death (c. 323 BCE) with Seleucus I Nicator entering into a treaty with Chandragupta years later. Seleucus Nicator, under this treaty, gave up Arachosia (Kandahar), Gedrosia (Makran), and Paropamisadae (Kabul) to Chandragupta, in exchange for 500 war elephants.

The texts do not include the start or end year of Chandragupta's reign. According to some Hindu and Buddhist texts, Chandragupta ruled for 24 years. The Buddhist sources state Chandragupta Maurya ruled 162 years after the death of the Buddha. However, the Buddha's birth and death vary by source and all these lead to a chronology that is significantly different from the Greco-Roman records. Similarly, Jain sources composed give different gaps between Mahavira 's death and his accession. As with the Buddha's death, the date of Mahavira's death itself is also a matter of debate, and the inconsistencies and lack of unanimity among the Jain authors cast doubt on Jain sources. This Digambara Jain chronology, also, is not reconcilable with the chronology implied in other Indian and non-Indian sources.

Historians such as Irfan Habib and Vivekanand Jha assign Chandragupta's reign to c. 322-298 BCE. Upinder Singh dates his rule from 324 or 321 BCE to 297 BCE. Kristi Wiley states he reigned between 320 and 293 BCE.
