How this is calculated
due ≈ last period + 280 days + (cycle − 28) (Naegele’s rule)
2026-01-01 + 280 days = 2026-10-08
Only ~4% of babies arrive on the exact date — most within two weeks either side.
Computed on your device — nothing is sent anywhere.

Questions about pregnancy due date
Yes — no watermark, no daily cap, no signup. Pro raises the file-size and batch limits, but the tool itself is not gated.
No. This tool runs entirely in your browser. Open your network inspector and watch while it works — there are no file uploads, because there is no upload endpoint.
Up to 10 files at 15 MB each. Everything runs in your browser, so the real ceiling is your device’s memory — the cap keeps a large file from exhausting the tab.
