Veradate

Ever sent a meeting invite that said "Thursday, February 18" — but February 18 was actually a Wednesday?

Veradate catches that mistake before it causes confusion.

It reads the dates on any page you visit and quietly checks whether the written day of the week matches the actual calendar. When something's off, it flags it with a red dotted underline — just like a spell checker — and shows you what's wrong.

Hover over any underlined date and Veradate tells you: "February 18, 2026 falls on a Wednesday, not Thursday." That's it.

What it catches
- Wrong day of the week paired with a real date
- Dates that don't exist — like February 30, or February 29 in a non-leap year
- All common formats: Thursday Feb 18, 18 February 2026 (Thursday), Thu, Feb 18 2026, and more.
- Abbreviated and full day and month names
- Dates that mismatch day of week that do not include an explicit year (assumes the current year)

Veradate runs like a spell checker: it scans text once when a page loads, watches for new content on dynamic pages, and gets out of the way. It does not slow down your browser or interfere with any page functionality.
