Sprints, deadlines, capacity, meeting load — the arithmetic behind every status report, typed in one line.
Project math is duration math: what's left of the sprint, how many days to the release, how much capacity the meetings ate. TCalc answers each as a single expression — no spreadsheet, no date-picker forms.
Dates subtract like numbers, durations convert between units, and custom converters can make a "day" mean 8 working hours.
Sprint time remaining after work burned so far.
Days until the release date.
Four workshop blocks of capacity.
The real weekly cost of daily stand-ups.
Subtract them: 2026-12-24 − 2026-07-17 = 159 days. TCalc parses dates directly, so countdown math needs no calendar clicking.
Subtract burned time from the sprint length: 14d − 3d 4h = 10D 20h. Save "Sprint = 14D" as a custom button and it's one tap.
Yes — built-in conversion treats a day as 24h, and custom converters let you define 1 day = 8h so 1 week = 40 hours, matching real capacity planning.
