Party Timeline Generator
Tell the tool how much time you actually have. It will prioritise the remaining decisions instead of scolding you for missing an arbitrary eight-week deadline.
Why the tool works in stages
Some tasks depend on other tasks. A sensible order is usually: establish constraints → invite → estimate attendance → plan quantities → shop and prepare → set up. Starting late means compressing that sequence, not pretending past deadlines are still useful.

How to read this estimate
The calculator separates your inputs from editable planning assumptions. Treat the result as a starting quantity, then adjust it for the real guest mix, product size, venue or serving style. See how our calculators work.
