# 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.

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.
