Septembris ASV iezīmē vārdadienas ar plašu personvārdu un to variāciju klāstu. Daudzos datumos, piemēram, 29. septembrī Maikla vārdu variācijām, ir apvienotas vairākas viena saknes vārda formas. Ievērojamās dienās ir arī 8. septembris ar Adrians vārdu variācijām un 9. septembris ar Jaden/Jade. Mēnesis unikāli atzīmē "Patriotu dienu" 11. septembrī, nevis individuālus vārdus. Kopumā saraksts parāda bagātīgu gan bieži sastopamu, gan retāku vārdu daudzveidību visa mēneša garumā.
