Appointment Gap Filler

Find openings in hours you confirm, from appointments you already hold. Drafts stay on this page until you copy them yourself.

1. Timezone and dates

Pick a listed zone. Years 2020 through 2035 only. Every appointment time needs an offset such as -04:00. A clock time that is skipped or repeated is refused unless the offset picks one real instant.

2. Hours, breaks, buffers

Mark a day closed, or give both open and close as 24-hour HH:MM. Breaks use one line each: dow 1 12:00 13:00 lunch (0 is Sunday) or date 2026-06-15 15:00 15:15 pickup. Holidays are one YYYY-MM-DD per line.

3. Appointments you already have

Paste CSV or choose a file. Required header: appointment_id, starts_at, ends_at, status, service. Status is booked, confirmed, completed, cancelled, or blocked. Example time: 2026-06-15T09:00:00-04:00. No names, email, phone, or web addresses.

4. Confirm before any opening is listed

5. Openings and drafts

Nothing computed yet. Nothing is stored.

Downloads are files on this computer. A change after generate turns them off and marks earlier files stale. Spreadsheet formulas are prefixed in the CSV only, so a sheet treats them as text.

Not on sale. Proposed later prices are $10 do-it-yourself or $29 per month for automation. This copy has no checkout, account, or entitlement.
