Description
Measure calendar lead time from a supplied public-notice posting to an event.
Community records describe contributions, volunteer time, grants, notices, language requests and meeting participation. Person-minutes differ from elapsed task time, assigned in-kind values require a valuation basis, and a nominal seat count need not be a whole-person allocation. Supplied participation or permission flags do not verify actual access, consent or eligibility.
Measure calendar lead time from a supplied public-notice posting to an event.
When to use this tool
Use Public Notice Posting Lead Time when you already have postingDate, eventDate and need to measure calendar lead time from a supplied public-notice posting to an event.
How to use the tool and how it works
- Enter postingDate, eventDate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.

}Limitations and assumptions
- Negative gaps are retained. No notice, publication, legally required period, event or public access is verified.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Review the underlying meeting, funding, service and volunteer records with the applicable project rules. Use full budgets, schedules and participation evidence when evaluating delivery or fairness; local labels and arithmetic retain only the stated assumptions.
