Her fever put a kibosh on Saturday dinner plans. His stomachache spoiled your girls’ lunch. The neighbor’s kid has sniffles, so there goes the playdate. Yes, you’ve learned to fill your calendar in pencil.

But some dates deserve to be etched in something more permanent.

Dalla Nonna jewelry has just the fix: a calendar necklace. Inspired by vintage tie pins, the tiny charms (about half the size of a key) acknowledge big dates.

The pendants come in silver or gold (rose, yellow, and white). You designate month and day, choose matte or shiny finish, and select a colored sapphire. If your daughter was born in June and your son in April, order one for each month and request the chains at different lengths.

That way, you can wear one lower down.

In case something else comes up.
