Count Course Absence Headroom From a Minimum You Supply
A rule written as a minimum attendance percentage can be hard to translate into remaining sessions. Convert the course’s stated minimum to a whole absence allowance and subtract absences already recorded.
1 · course | scheduled sessions | absences to date

Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the attendance headroom ledger: your course | scheduled sessions | absences to date stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Only sessions covered by the rule belong in the denominator. After: the attendance headroom ledger shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Optional AI formatting, not calculation
For this attendance headroom ledger, an external AI text tool may help format non-sensitive notes if you already use one. No AI service or account is required: manual entry completes the same free core calculation. Do not paste private or sensitive data. Review every value against the source before using it.
Format my non-sensitive notes for a attendance headroom ledger. Return plain rows only: course | scheduled sessions | absences to date. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
Accepted schema: course | scheduled sessions | absences to date. No AI response is executed as code.
