The record for the youngest and fastest to identify the day of the week for any given date was achieved by Medhansh Virmani (Age: 12 years & 10 months), S/o Tarun Virmani, native of Gurugram, Haryana, India. His fascination with calendars at a young age grew organically into a sophisticated cognitive skill, enabling him to recognize patterns in dates and mentally compute the day of the week with startling ease. Medhansh’s exceptional calendar memory was tested live by the adjudicators of the High Range Book of World Records, where he was able to answer the questions in just a few seconds, and the record was approved on 28 July 2025.
