Insignificant Anniversary

Anniversaries are a celebration held every year after a significant event. However, in this case, it's a bit... different. Maybe instead of a year after, it's just a week.^note Although in that case it would not be an anniversary; annus means "year". Maybe instead of a significant event, it's something comparatively minor that no one would think to celebrate. In fiction, it's most commonly manifested by something like celebrating a week of a relationship, or something similar.

There are several reasons for this. First of all, if it involves a romantic relationship, it shows at least the partner who initiates the celebration is very in love with their lover. Of course, if it's mutual, this can be used to show the couple is Sickeningly Sweethearts. On the other hand, past incidents that are significant to the character(s) may not appear to be significant to the viewer, and this trope helps establish its importance.

Can overlap with Milestone Celebration if it's celebrating some aspect of the show itself, like the number of episodes.
