Why can't I open the downloaded software China Almanac?

All kinds of "old yellow calendars" are not published by authoritative departments.

Seriously, it's not accurate. It's often the same day. This calendar says good luck and that calendar says bad luck.

People who are willing to live according to the imperial calendar, according to their own preferences, look for one is one.

People who don't believe in the old almanac can ignore it.
