Does Mail Run On Sunday

Will the post go to another country on Sunday?

In most countries the post office is open 24 hours a day, 7 days a week, but they only ship six or five and a half days a week, no one knows why, but perhaps unions, even private companies like Fedex and UPS On Sunday, the ship, when everyone is home from work, no postal service noticed that workers were present in the morning and evening while the company was busy during the day.

Mail travels to the United States on Sundays. My aunt, uncle and brother-in-law work for the United States Postal Service and send mail on Sundays. Until christmas
