Latvian NameDays in May showcase a diverse collection of names, with the majority appearing uniquely on their respective dates. Some names, however, celebrate twice, including Ziedone, Ina, Inese, Inesis, Sibilla, Venta, Anslavs, Gunita, and Henrijs. The month fittingly begins with nature-themed names like Ziedite and Ziedone, and also features Maija on the tenth. This tradition provides a rich and varied cultural calendar for the month.
