Daily Devotional Planner Calculator

This calculator takes a single total-minutes budget and splits it four ways using percentages you control for three of the categories, with the fourth — meditation — automatically absorbing whatever percentage is left over (the code runs that remainder through Math.max(0, ...), so meditation simply disappears instead of showing a negative number if your other three percentages already add up to more than 100). Each category's minutes are simply your total daily minutes times its percentage share; there's no hidden weighting or adjustment beyond that direct proportion. Weekly and monthly totals are plain multiplication too: your daily minutes times 7 for the week, times 30 divided by 60 for a rough monthly hour figure — a 30-day approximation rather than a true calendar-month calculation, so it will run slightly short in 31-day months and slightly long in February. The estimated pages read per session is the least precise output here: it assumes roughly one page of reading per minute, a rule-of-thumb figure loosely built around a ~250 words-per-minute reading pace against a page holding around 250 words, which will vary a lot depending on your Bible's typeface, translation, and whether you're reading straight through or pausing to reflect.

The real value of this tool isn't precision math — it's forcing an explicit tradeoff. If you set prayer, reading, and journaling percentages that already add to 100%, meditation time disappears entirely, which is a legitimate choice for some devotional styles but worth noticing rather than defaulting into by accident. Adjust the sliders and watch how a few extra minutes in one category quietly steals from the time available in the others.
