Arvind spent eighteen months on it. He quit his job. He sourced a low-power, e-ink display from a discontinued e-reader factory in Shenzhen. He programmed an ATmega328P microcontroller—the same heart as an Arduino—with a stripped-down version of the Swiss Ephemeris. No Wi-Fi. No Bluetooth. No touchscreen. Just raw, precision astronomy compressed into 512 kilobytes of flash memory.
Unlike solar days, which strictly last 24 hours from midnight to midnight, tithis vary in duration. A single tithi can last anywhere from 19 to 26 hours. Because lunar cycles do not align perfectly with the 365-day solar year, Hindu festivals and tithis shift on the Gregorian calendar every year.
