Calibration due date calculator

Parses a pasted instrument register and computes calibration due dates from last calibration plus interval, flagging overdue and due soon items, with CSV and calendar file exports.

Instrument register, one per line

Read in this tab only

Paste your instrument list, one per line, and the register builds itself: due dates from last calibration plus interval, days remaining, overdue and due-soon flags, and a CSV or calendar download for the quality system.

Register settings

Back-date it to answer audit questions
0 to 365; 30 is the usual default

One instrument per line: ID, description, last calibration (yyyy-mm-dd), interval in whole months, then optional owner and location. Lines starting with # are comments. Up to 500 instruments, 300 characters a line, 150,000 characters a paste.

Runs on this device. Nothing is uploaded.
