Section 16 Deadline Calculator
Tiny SEC Forms 3, 4, and 5 date planning with memo and CSV export.
Section 16 Deadline Calculator is a tiny local-first web tool for estimating common SEC insider reporting target dates. Choose Form 3, Form 4, or Form 5, enter the trigger date, add any extra SEC closure dates, and copy a source-linked planning memo or CSV row for a legal, compliance, issuer-ops, finance, or EDGAR filing checklist.
I built it because Section 16 date checks are short and easy to miss: Form 3 uses a 10-day initial ownership window, Form 4 uses a two-business-day transaction reporting window, and Form 5 uses a 45-day fiscal-year-end catch-up window. The tool keeps that worksheet focused and local: no signup, no cookies, no analytics, no beacons, no external scripts, no uploads, and no browser storage.
Say goodbye to SEC filing headaches with this nifty deadline calculator that keeps your Forms 3, 4, and 5 on track, complete with memos and easy CSV exports—all without any signups or tracking. Perfect for insider transaction pros who love saving time and sanity!
Key features:
- 🔥 Browser-only with no signups, cookies, or tracking
- ⚡ Handles weekends, US federal holidays, and custom closures
- 🎯 Exports memo, CSV, and ICS calendar files for seamless planning
- 🕒 Precise Form 3, 4, and 5 deadline calculations with EDGAR cutoff awareness
