This World Record is for calculating the exact day of 60 random dates of ten Billion years calendar in 60 seconds only.
Given a date and day in a particular year, he can tell the months in which such combinations occur, e.g. 1986, 22 Saturday: - February, March, and November. In a block of five years, given day, date, and month he can tell the year. For any given year, he can tell the first and last day of all the months. If given a combination of month, date, and day, he can tell the years in which it occurs.
He created the record by making and memorizing the World’s Longest Unlimited Years Calendar. The calendar is based on the coding system to find the day of any date starting from 0001 up to infinity. He also discovered the method to memorize the complete unlimited years calendar in just one hour, anyone can tell the day of any date without looking at the calendar mentally.
