Ida's name day is observed across numerous countries and dates throughout the year. The celebrations occur on February 3rd in Latvia and February 16th in Slovakia, followed by March 15th in Czechia. April 13th is a widely recognized date across several nations including Austria, France, Croatia, and Poland, while May 8th is noted in both Austria and Croatia. September 4th holds significance in the USA, Norway, and Poland, with a further date on September 14th in Sweden and October 29th in Croatia.
The name Ida is a feminine appellation of Germanic origin, tracing its roots to elements meaning "industrious" or "prosperous." In the USA, the name enjoyed peak popularity as a traditional favorite during the Victorian era, particularly around the 1880s, before a significant 20th-century decline. Carrying a mood that is classic, simple, and quietly elegant, Ida suggests a grounded and determined personality. Its short, two-syllable structure provides strength while maintaining a soft sensibility. Ida is universally categorized as a female name worldwide. This vintage charmer is currently experiencing a modest revival among modern parents.
