Which is the yellow calendar?

There are several upstairs. Do not mislead the landlord.

The Gregorian calendar follows the natural way, so twelve hours are divided according to the sun, not according to Beijing time.

For example, you can't say that the sunrise from 3: 00 to 5: 00 is Shi Mao, because in some places, the sun doesn't rise from 3: 00 to 5: 00.

Therefore, local time must prevail. Remember, remember.
