How long does it take (approximately) for a letter to reach Frankfurt from Paris? I'm assuming it's about the same in the opposite direction, but correct me if it's not for some reason.
We googled "Paris Frankfurt mail", "Paris to Frankfurt letter", "Frankfurt to Paris letter", "european mail times". And I checked the French and German mail service sites, but I couldn't navigate them very well.
Thanks in advance,
ETA: Is there mail service on Sundays in Europe?
We googled "mail sundays france" and "mail sundays germany"
