A conception calendar is used to estimate when a baby was conceived. It usually uses the date of a woman's last menstrual period to estimate conception and due date.
Our calendar is incompletely inaccurate.
The Egyptians developed the first accurate calendar.
The calendar system widely used today, known as the Gregorian calendar, was developed by Pope Gregory XIII in 1582. It was introduced to reform the earlier Julian calendar, which had inaccuracies in calculating the length of the solar year. The Gregorian calendar corrected these discrepancies by adjusting the leap year system, leading to a more accurate alignment with the seasons. It has since been adopted by most countries around the world.
No, a leap year does not affect the biological processes of conception or pregnancy. The likelihood of getting pregnant is influenced by factors such as ovulation timing, overall health, and reproductive conditions, rather than the calendar year. Leap years simply add an extra day to the calendar and have no impact on fertility.

The most accurate calendar system used globally is the Gregorian calendar, which is the most widely used calendar system in the world today. It was introduced by Pope Gregory XIII in 1582 to correct inaccuracies in the previous Julian calendar. The Gregorian calendar is based on the solar year and is more accurate in aligning with the Earth's orbit around the sun.
The development of the accurate calender was in 450 B.C.
The Mayans
The Aztec calendar recognised 365 days
they were just as accurate as the one we use now with 365 days
