What is the Turtle Brumation Planner?
The Turtle Brumation Planner plans a safe brumation schedule and temperature drop for turtles. Small, regular health checks and a consistent care schedule catch problems earlier than waiting for obvious symptoms to appear.
A well-cared-for turtle usually lives somewhere between 20 and 40 years. As an omnivore, what a turtle needs from its diet changes across its life stages. Aquatic turtles need far more water than most owners expect, roughly 40 liters per 2.5cm of shell, with powerful filtration, a dry basking platform and UVB. They are a multi-decade commitment that commonly outgrows its first tank. Keep an eye out for shell rot, metabolic bone disease from missing UVB, vitamin A deficiency and swollen eyes. These are the conditions turtles are most commonly seen for.

How does the Turtle Brumation Planner work?
Where a schedule is produced, it follows commonly recommended cadences for turtles; where a score is produced, it uses a simple, transparent scale rather than a black-box formula. Use it to know roughly where you stand and what to ask about, not to rule anything in or out on its own.
What changes the answer
- Age: younger and senior animals typically need more frequent checks than a stable adult
- Existing health conditions: which may call for a tighter schedule than the general default
- Lifestyle factors such as indoor/outdoor access, which affect exposure to parasites and injury
- Your veterinarian's specific recommendations, which should always take priority over a general default
How do you use the Turtle Brumation Planner?
- Pick the date this was last done
- Answer "How often do you want to repeat it?"
- Answer "How many dates to plan ahead?"
- Answer "How demanding is this animal's routine?"
- Press Calculate, then read the result alongside the sources listed below
Worth doing: jot down the date and the result each time. A single number tells you little, but a trend across a few months tells you a lot about your turtle.

Before you rely on this
Averages hide a lot of variation. The figure here reflects what is typical for turtles, but your turtle may sit well outside it for perfectly ordinary reasons. Use the result to spot changes over time in your own animal rather than to compare it against other people's pets.
