Is there a 33 year cycle?

Over the course of 33 years, there will be a lag of one year between solar and lunar calendars because of the successive epacts. We named it as 33 cycle. We call the time period required for Earth to complete one revolution around the sun a solar year. A solar month means one twelfth of a solar year.
How long can you travel through a wormhole?
Time travel through a wormhole is possible in increments of 33 years, because the wormhole is only activated when the sun and moon align (which happens every 33 years). For example, from 1986 one can travel 33 years in the past to 1953 or 33 years in the future to 2019.

In summary, the only real astronomical quantities involved are the lunar month and the solar year.

Moon takes 354 days to pass through all its phases (new moon, half moon, full moon) i.e., in moon 1 year = 354 days (this is according to lunar calender) We know according to solar calender, 1 year = 365 days. 365–354 = 11. So there is a difference of 11 days between both calenders.

What is the problem with the lunar calendar?

How many days are there in a lunar month?
In order to stay correct, every lunar calendar has to deal with this drift away from the calendar year. Let’s examine a year. A lunar month lasts 29.53 days. So after 12 lunar months, you’re about about 354 days. This is short of the 365 days that it takes the Earth to orbit the Sun.
How long does it take for the lunar calendar to work in China?
This is short of the 365 days that it takes the Earth to orbit the Sun. This is a problem since after about 3 years, the lunar months are out of cycle with the solar year by about a month. And this problem would just continue. To make the lunar calendar work in China, farmers would add in a leap month every 3 years.

Do lunar calendars use intercalation?

How does the length of each lunar cycle vary?
