Free SEC date tracker
Estimate the standard Form 8-K Item 4.01 four-business-day target date for auditor-change account-research rows, then copy a source-linked note or CSV row for follow-up tracking.
Turn an auditor resignation, dismissal, refusal to stand for reappointment, or new-auditor engagement date into a follow-up date for research queues.
Form 8-K General Instruction B.1 says most reportable events are filed or furnished within four business days unless a different item-specific rule applies.
A date estimate, status note, Markdown research memo, and CSV row that can connect to the watchlist and evidence-pack workflow.

Deadline tracker actions: 0
Use the earliest event date reported in the filing for the estimate, then compare the actual Form 8-K filing date only as a research status check.
The calculator skips weekends by default. Add SEC closure or holiday dates manually when the event window crosses one.
Use the result to prioritize source review, not to accuse a registrant of lateness or make trading, issuer-quality, or auditor-quality claims.
Copy the CSV row into the watchlist, then build a separate evidence pack once the filing text and source URL are verified.
The SEC Form 8-K PDF is the primary source for the four-business-day timing language and the accountant-change item. Investor.gov provides a plain-English summary of Form 8-K timing for investors. This tool links those sources but does not interpret company-specific obligations.
