What do “a

What do “a.m.” and “p.m.” mean? This is unbelievable. A post on X went viral asking that question. In case you don’t know, “a.m.” stands for “ante meridiem” (Latin for “before midday”), and “p.m.” is “post meridiem” (“after midday”). I’m shocked by how many folks are surprised 12 p.m. is noon and 12 a.m. is midnight. How does this happen?
