In part 9 of our 10-part anniversary series, we’ll attempt to figure out when King Agnarr’s birthday might be! We got this anon question a while ago!

First and foremost, thank you for your question, anon! Agnarr’s birthday is a bit of a mystery and we can’t seem to reach a consensus about it even in our server 😂 I don’t recall that we have any specific mentions of when exactly during the year it might be, unlike Anna, Elsa, Olaf and Iduna’s birthdays. But we will do our best to bring us closer to an answer. The book you’re thinking of is called The Mysterious Treasure (Valentina Cambi, 2022) and does indeed feature Anna and Elsa preparing for Agnarr’s birthday:

Right pic above is a translation of the French version. Also, Rolf the rocking horse is there!

In the English version, the text is worded in a slightly different way: It was a special occasion: the birthday of Elsa and Anna’s father, King Agnarr. To celebrate, they headed into the castle attic to look for old memories. There, in a comer, they found a trunk that they had never seen before! “This chest belonged to Father!” Anna exclaimed, recognizing Agnarr’s royal symbol carved into the lid. “What could be inside!” Olaf asked. “Let’s find out!” suggested Elsa. Neither version goes into further details about what time of year it is. And even if it did, we of course don’t know exactly when his birthday is in relation to the story. Judging from the illustrations though, the trees are fully green and there appears to be at least some flowering plants in the background. In southern Norway, trees typically turn green in late April and early May (same as in Sweden where I’m from) and start to turn yellow in late September and early October. So, solely based on the illustrations in the book, we can safely say that Agnarr’s birthday is between May and September. Several server members presented the theory that Agnarr’s birthday would be on or close to the September equinox (September 21 to 24), to mirror Anna and Elsa’s summer/winter solstice birthdays! Iduna’s birthday is theorised to be close to the March equinox at the end of winter according to Anna and Elsa’s Winter’s End Festival (Amy Weingartner, 2014) and The Winter Festival (Valentina Cambi, ca. 2021) so it would give us a perfect “symmetry” of birthdays😀 The only other indicator we know of for when his birthday logically must be is that he must have turned 21 at the time of his coronation.

Dangerous Secrets (Mari Mancusi, 2020) only makes a few references to Agnarr’s coronation and only in terms of being “in three years” from a time when Agnarr is 18 years old. So, yes! The theory that King Agnarr is born near the September equinox holds up!
