Why are All Umamusume’s Birthdays at the Beginning of the Year?

It’s interesting to note that most of the horse-girl characters appear to be born between March and May, with some exceptions from January to June. This pattern arises because the Umamusume share their birthdays with their real-world counterparts, horses. In the Northern Hemisphere, horses typically have their breeding season during spring, and they are pregnant for about 11 months. Since all these horse characters originate from the Northern Hemisphere, it’s common to find them born around March and April.
How Old Are the Umamusume Horse Girls?
As a gamer, I’ve recently learned something fascinating about my favorite anime, “Umamusume: Pretty Derby”. During a live stream, the creators revealed an intriguing detail: the horse girls in this series essentially don’t age at a consistent rate, much like elves. This means they grow as the story demands, which is quite unusual and adds to the show’s charm. A redditor named magolor98 brought this up, pointing out that instead of having typical growth spurts, these characters seem to experience sudden growth leaps, implying that they seldom age in the conventional sense.

As a dedicated fan, I’ve noticed an intriguing aspect about these virtual equines: they seem to have no connection to the actual horses’ birth years, starting racing years, or their age when they first began racing in real life. Instead, it appears as if the developers have given them any age they desired, and have made it so these horses will never grow old or perish. This seems to coincide with the typical Umamusume race duration in career mode, suggesting that their ages were intentionally designed to fit this narrative.
