Common Scenarios & Troubleshooting

Note on errors: the most common slip-up here is an off-by-one date or a typo in a number that throws off the whole result. If that happens, double-check your input rather than the tool — the calculation itself runs the same way every time.
Your data stays private. Everything you type runs locally in your own browser tab. Nothing is uploaded, logged, or stored on a server — close the tab and it's gone.
Behind the Scenes: The Processing Logic
This tool processes everything client-side, inside your browser window, using structural pattern checks against your input, comparing bracket and quote counts the same way a parser would. Live calculation updates testing contrast equations instantly Nothing is sent to a server, so there's no upload delay and no privacy trade-off.
