Watch Weeks vs WhichWeek

** If the Watch Weeks App does not show up on your Watch after purchase, you might have disabled "Automatic App Install" in your Watch App. You have to download the Watch Weeks App in the App Store on your Apple Watch directly. ** With Watch Weeks you can display the current calendar week on all your watch faces as a complication. The App allows you to scroll through the passed and up coming weeks to display the week difference along with the start and end date of the week.
