Episode 21 of Ancient Code, Modern Mind tunes Aryabhata’s Kālakriyāpāda, his cosmic pocket watch, in 499 CE Pataliputra. Host Harsh Rain evokes the Gupta Golden Age—bustling markets, Nalanda’s debates, Ujjain’s star charts—where Aryabhata, a 23-year-old clockmaker, unraveled time’s tangle. Verse 5 defines four time systems: solar years, lunar months, civil days, and sidereal days, syncing seasons to festivals like Diwali. Further verses and methods add leap months and skip lunar days to align calendars, stretch time to 8.6-billion-year Kalpas, and anchor it to the Kali Yuga’s start in 3102 BCE. Leaning on Episodes 13–18’s math, Harsh connects Aryabhata’s gears to GPS, Mars missions, and calendar apps, weaving time into a cosmic song. A lunar-phase challenge, Cosmic Clock Quiz, and epicycle teaser spark engagement, while Episode 22’s planetary dance beckons, inviting listeners to waltz with Aryabhata’s heavens.
