is there a word for daily or weekly anniversaries?
Your difficulties in your search may stem from the fact that the Roman calendar did not have weeks as we know them. However, since the Romans went around conquering people who did use weeks, they seem to have come up with at least one Latin word that I could find that expresses the concept: hebdomas, hebdomadis, a word that persists in later Latin, where Holy Week is Hebdomada Sancta and a hebdomadarius is one who performs certain duties within their order for the week. On the basis of my research, then, I propose the awful mouthful hebdomadariversary, although it’s quite possible that someone with more formal knowledge of Latin may be able to correct me on the proper formation of such a word. Either way, I hope your turkeys appreciate it
