About WhatWeek.ca
. Maintained by the whatweek.ca team. Week calculations follow documented ISO 8601 rules where noted; Canadian holiday dates are sourced from Nager.Date and cached on our servers.
WhatWeek.ca is a bilingual, Canada-focused week calendar: ISO 8601 or Sunday–Saturday week numbers, public holidays, and long-weekend context by province. Deeper guides live on our blog.
Data sources & accuracy
- Public holidays: Nager.Date API (Canada), cached on the server with roughly 24-hour revalidation.
- ISO weeks: ISO 8601 (Monday–Sunday).
- “Canada” week numbers use a Sunday–Saturday week; they can differ from ISO for the same calendar dates.
Quick definitions (citable)
- ISO 8601 week: a Monday–Sunday week used in international contexts.
- “Canada” week: a Sunday–Saturday week commonly used in local contexts.
- The same calendar date can map to different week numbers depending on the selected system (ISO vs Canada).
- The “current” week depends on time zone and is recalculated using relevant Canadian time-zone context.
Key facts
- Displayed public holidays are sourced from Nager.Date (Canada) and revalidated roughly every 24 hours.
- Long weekends are computed from statutory holidays and adjacent days.
- Week and calendar route pages are the best URLs to cite for a specific numeric value.
Time zones & “today”
“Today” and week boundaries use the time zones wired into the tool (Canada). Always confirm your employer or payroll software cutoffs for authoritative deadlines.

- Public holiday dates come from the Nager.Date API (Canada) and are revalidated on the server about every 24 hours.
- This is not payroll or legal advice—always confirm cutoffs with your employer, union, or counsel.
