About calendars:
- Gregorian calendar is the most popular calendar in the world. It's a calendar based on 365 days divided into 12 months. About every four years is a leap year when one extra day is added to February, making the leap year 366 days long.
- Julian calendar is a dating system established by Julius Caesar to reform of the Roman calendar. The Julian year is, therefore, on average 365.25 days long, and has two types: normal years and leap years.
The current inconsistency between Julian and Gregorian calendars is 13 days. But, the difference will become 14 days in 2100.
- Lunar calendar is a calendar based upon the monthly cycles of the Moon's phases, a lunar year, is only 354 days, 8 hours, 48 minutes, 34 seconds.
Your Lunar Age = current year in lunar calendar – your birth year in lunar calendar + 1.
