See Volunteer Shift Coverage Before the Event Begins
A sign-up name does not reveal overlap, a handoff gap, or whether a shift was confirmed.
Map volunteer shifts by day, start/end time, role, and confirmation status; show uncovered time and overlaps.
What changes the result: your event's own roles, volunteer availability, and confirmed arrival times.
Privacy: Calculations run in this browser tab. This tool has no input-upload, account, or AI endpoint. The site may send a page-view signal to Cloudflare; this tool does not add form entries to that signal. A draft is stored only if you choose “Save draft on this device”; that browser storage is not encrypted. Avoid identifiers or sensitive details, and delete saved drafts when finished.
Your entries
The starting rows below are fictional examples. Edit them, replace them with non-sensitive labels and values, or load the sample again. The result is not advice or a source verification.
Amount fields use the same units you enter; the app does not choose a currency. Dates are the ones you provide. Up to 100 rows per run.

What the calculation does
Parse same-day local clock times, group entries by date and person/resource code, and mark overlapping active intervals. Overnight work must be split into separate entries. No travel time or time-zone conversion is inferred.
Question to keep open: Should every shift be staffed to capacity or should the plan include a backup for the jobs that cannot pause?
Boundary: This is a personal organization aid, not legal advice, eligibility guidance, an official agency record, or a deadline calculation. Verify requirements, contacts, and dates with the responsible official source or a qualified navigator.
Copy includes the headline, aggregate metrics, and boundary—not the row-by-row input. The CSV contains entries you choose to download. Review it before sharing.
