What you’ll find here
This page gathers Pelavault’s everyday living tools — the calculators that don’t fit a single nutrient or activity, but still help you put useful numbers on daily routines. There are three: a 30-day habit planner, a bedtime planner for older adults, and a kitchen volume converter.
Like every tool on this site, they are transparent, reference-based estimators. They recompute well-known public figures — habit-formation guidelines, published sleep-duration ranges, and standard US customary volume definitions — and show their arithmetic openly. They set no targets, make no recommendations, and replace no professional judgment.
30-Day Habit Calculator
Building a routine is a planning problem before it is a willpower problem. This tool turns a goal — reading daily, walking more, drinking water regularly — into a 30-day plan: you set the target, how many days per week, and session length; it estimates total effort and a consistency score across the month.
Bedtime for Senior Calculator
Sleep timing is a clock question, and this tool treats it that way: enter a desired wake-up time, and it works backwards through the sleep-duration ranges published for older adults (60+) to suggest a bedtime window. No gadgets, no trackers — just published ranges and straightforward arithmetic.
Cup to Gallon Conversion Calculator
The quiet workhorse of the site. Scaling a recipe, portioning a bulk ingredient, or translating a daily water-intake figure into containers you actually own — all of it eventually needs cups converted to gallons (or back). This tool does the conversion instantly using the standard US customary definition, both directions, any quantity.
What these tools can and cannot do
- They can turn published reference figures — habit-planning guidelines, sleep-duration ranges, fixed conversion definitions — into quick, checkable answers.
- They can help you compare two candidate plans or schedules on the same basis before committing.
- They cannot know your personal circumstances, and they set no targets for you.
- They cannot replace professional judgment. Anything that matters to your circumstances deserves a conversation with an appropriate professional.

Frequently asked questions
Are these three tools related to each other?
Loosely — they all put numbers on daily routines, which is why they share a page. The habit planner covers a month of effort, the bedtime planner covers a single night’s timing, and the converter covers kitchen units. Each stands entirely on its own.
Where do the underlying figures come from?
The habit planner uses standard planning projections (targets × frequency × duration). The bedtime planner uses published sleep-duration ranges for older adults. The converter uses the fixed US customary definition (1 gallon = 16 cups). Every tool page states its own basis explicitly.
Is the conversion tool exact while the others are estimates?
Yes — and that difference is worth understanding. Unit conversion is a fixed definition, so it’s precise. The habit and bedtime tools scale published guideline figures, which makes them reasonable estimates rather than exact answers. Each page labels which kind it is.
Can I check the math myself?
Yes. The habit planner shows its projection arithmetic; the bedtime planner shows the subtraction from your wake time; the converter shows the multiplication by 16 (or division). Nothing is hidden.
