How to use this calculator
Enter your word target, drafted words, weekdays and exclusions. Choose deadline balancing or a daily word pace and set whole revision dates.
Deadline mode balances whole words across drafting dates before reserved revision dates. Pace mode drafts up to the entered daily target before moving to revision. Missing words and revision dates are reported.
A worked example
From November 2-30, 2026, Monday-Friday availability gives 21 dates. Reserving three for revision leaves 18 dates to draft 10,000 remaining words.
Does revision happen on the last drafting date?
No. Revision uses later available dates. If the draft is already complete, only the entered revision work remains.
Which calendar and years are supported?
Use Gregorian dates from 1900 through 2100, with results in that range. Daily plans allow up to 366 dates; dark-sky searches allow 31 nights. Durations, capacities and policy rules are supplied by you. Astronomy uses the bundled Astronomy Engine, sea-level geometry and browser time-zone rules. Timed exports use UTC instants; date-only events do not assign a clock time. Copy, CSV and print include calculation assumptions. Nothing is booked or scheduled outside this page.
What happens to my dates?
