Compact pocket calendar with only 24 pages.

This pocket calendar has only 24 pages and has broken the previous record of an Australian who invented a calendar that can see the next 400 years. Inside the calendar is not a specific calendar for each year but records the formula for calculating future dates according to the law discovered by Mr. Muniraj.

Sharing his logic for calculating dates, Muniraj said: 'I was looking up the calendar for an event that took place in 1988. It was a leap year and I accidentally discovered the principle of dates . After careful calculations, I discovered that every century is the same, the date will be moved back by one day if it is a leap year. Just like that, I found the general formula for 100 years, 1,000 years and 100,000 years'.

Muniraj, who dropped out of school after the 10th grade and worked as a proofreader before retiring, hopes his invention will be used in research in various fields such as astrology and mathematics. Muniraj's 2-billion-year-old calendar has received many awards from local authorities.
