Horses of Hoofprint Bay Horse Age: Days, Yearlings, Retiring

Horses of Hoofprint Bay horse age confuses almost everyone at first: open a horse's info and you may see an age of 60, or even 97. Horses of Hoofprint Bay horse age is not counted in years at all, and once you know the unit, the breeding timings, sale prices and retirement rules all make sense. This guide collects what the in-game library and players have worked out.

Age decides when a foal becomes useful, how much a horse is worth and how long you can ride it, so it shapes almost every long-term decision on your yard. The official Horses of Hoofprint Bay store page on Steam describes breeding foals to improve your stock over time, and age is the clock behind that.

What Horses of Hoofprint Bay Horse Age Measures

When a player asked on the official Steam forum how a horse could be 97, another player explained that ages are counted in rounds of the game. A round is called a "day" in the game, but it doesn't equal a real day, and the in-game library has more detail on how horses age.

A full-release gameplay video shows the same thing: the starter horse was 60 when the player got it, and two in-game days later its info screen showed 62.

The office lets you keep track of the whole herd. In the same video, the horse list in the office can be sorted by confidence, strength, endurance, exercise, health, body condition, age, pregnancy, foals, experience and stable group.

Foal, Yearling and Adult: Age Stages

The in-game library lays out each stage. A mare is pregnant for 8 days. The foal then stays with its mother for 4 days before it grows up to a yearling, and the yearling grows up to an adult once it is 12 days old.

Players on the official Steam forum confirm the timing. A demo player reported that a foal born on in-game day 13 became an adult on day 25, which is 12 days. Another player explained that the yearling stays in the yearling pasture until day 12, and that you can train and care for it there. For the pregnancy rules and how foals inherit potential, see our Horses of Hoofprint Bay breeding guide.

Yearlings that grow up with nowhere to go

Plan space before a yearling turns 12. One player's yearling aged up in the yearling paddock while the stable had no room and was sent away; another player answered that you can find it at the sale barn in town. A different player who had a foal become a yearling before building the yearling paddock could not move it there afterwards and suspected a bug.

How Age Changes a Horse's Value

Horses of Hoofprint Bay horse age also changes how much a horse is worth. According to the in-game library, read out in a gameplay video, a horse has a base value of 100 plus a variable value that depends on its potential, training, prize money, health problems and age. The variable value is then multiplied by an age factor.

The same library text shows how much potential and training add: the sum of potential strength and endurance counts exponentially, from 0 to 7,000, and trained strength and endurance count linearly, from 0 to 4,000. The in-game money tips add that horses sell for more when they are well trained, but not too old. If you train horses to sell, sell them as young adults.

Horses of Hoofprint Bay Horse Age Limits and Retirement

Horses don't stay forever. The in-game library says a horse older than 180 can't be ridden or bred anymore, and it moves to the retirement farm at age 192.

Some players find this hard. In a forum thread about retirement, one player was sad that horses can't stay with you until the end, and other players said they read the retirement farm as the game's way of saying a horse has passed without saying it outright. That is the community's interpretation, not a developer statement.

Players have found a few ways to keep favorite horses around:

• The ferry: a player reported that the ferry in town lets you export horses for the same price as trading them, and import them again in a different save, so you could roleplay a retirement stable there.
• Boarding at the breeder: the May 2026 dev update says you can board additional horses at the breeder in town, as many as you can afford to pay board for. A player asking for a retirement field mentioned paying 100 a day for this.
• Selling earlier: since value drops for older horses, selling before a horse gets old returns more money.

Boarders and Age

Age matters for boarders too. One player reported that the boarders folder only shows "yearling" or "adult", not the exact age, so you can't tell when a yearling boarder will mature. That player took in a yearling mare that grew up the next day and was placed in the stallion pasture because the mares' pasture was full. If you keep stallions and mares apart, think twice before accepting yearling boarders when space is tight. More on boarders in our Horses of Hoofprint Bay boarders guide.
