Free bilingual tool delivers the ISO week number, start date, and end date instantly — no login, no clutter
MONTREAL, Canada — May 2026 — WhatWeek.ca is now live, offering Canadians a free, fast, and beautifully simple way to answer one of the most Googled calendar questions: What week of the year is it?
The site does one thing exceptionally well. Visit WhatWeek.ca and you immediately see the current ISO week number, the Monday it started, and the Sunday it ends. No ads blocking the answer. No calendar grids to decode. No scrolling. Just the information you came for.
The Problem It Solves
Week numbers are more important than most people realize. Payroll teams run on them. Project managers track sprints by them. Logistics coordinators schedule deliveries with them. Teachers build lesson plans around them. Yet for years, Canadians looking up the current week number have had to wade through cluttered calendar websites and generic search results to find a simple answer.
WhatWeek.ca was built to fix that.
“People search ‘what week is it?’ constantly and end up on pages that make them work for the answer,” said the site’s founder. “We wanted to build the page where the answer is the very first thing you see — clean, correct, and instant.”
Built for Canada, in Both Official Languages
WhatWeek.ca is fully bilingual, available in English and French, making it accessible to Canadians from coast to coast.
The site follows the ISO 8601 standard — the international format used in business, government, and academia — where weeks run Monday to Sunday, and the first week of the year is the one containing the year’s first Thursday. This is the standard used across Canadian industries and public institutions.
