Description
Partition a project interval against a funding interval.
Community projects combine participation counts, access assertions, funding bases and shared-resource policies. Local allocation or coverage arithmetic can organize those records, while equitable access, actual contribution value and valid funding rights require evidence and the applicable rules.
Partition a project interval against a funding interval.
When to use this tool
Use Project Funding Period Gap when checking one explicit community-project capacity, funding, access or scheduling convention.
How to use the tool and how it works
- Enter projectStart, projectEnd, fundingStart, fundingEnd. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read unfundedBefore, unfundedAfter, fundedDuration. Use the output convention below.
Partition a project interval against a funding interval. Require ordered endpoints in both; return overlap fundedDuration plus clipped unfundedBefore and unfundedAfter durations.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| projectStart | Project Start | Required. Finite number. |
| projectEnd | Project End | Required. Finite number. |
| fundingStart | Funding Start | Required. Finite number. |
| fundingEnd | Funding End | Required. Finite number. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| unfundedBefore | Unfunded Before | Required. Finite number. |
| unfundedAfter | Unfunded After | Required. Finite number. |
| fundedDuration | Funded Duration | Required. Finite number. |

}Limitations and assumptions
- Time units and eligibility periods are supplied; no funding entitlement, schedule feasibility or actual cash coverage is established.
- 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.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use actual project records, participant needs and governing funding/resource rules to assess practical adequacy, fairness and eligibility.
