Count days to an event or supplier milestone.
SubeR WORK / TOOLKIT
Build a budget and run-of-show. Plan dates and shared costs.

WORKSHEET / QUICK CALCULATION
Add fixed costs, guest costs and your own contingency allowance.
Base = fixed costs + guest count × cost per guest. Contingency = base × allowance ÷ 100, rounded to cents. Total = base + contingency; remaining = available budget − total. Negative remaining means over the entered budget. Include known fees/taxes in your costs; none are inferred.
WORKSHEET / QUICK CALCULATION
Add up to 12 blocks with a transition buffer between them.
Each block starts after the previous block and the entered buffer. There is no buffer before the first block or after the last. Whole minutes only; maximum total 7 days. Next-day labels show midnight crossings. This is elapsed clock arithmetic, not a dated calendar: daylight-saving changes and time zones are not modelled.
