Quick answer

A date and calendaring tool for Android

Do you need to convert between a week number and a date or require some information about a date? Find out if a year is a leap year, calculate the number of days, business days, weeks, weekends, month turns and years between two dates? Want to add or subtract days, weeks or months to a given date?

With TKWeek, it‘s no hassle. Even a basic calendar view is at your fingertips. You can use it to flag days off. Just tap and hold until the color changes. And with My Day you see what is up on a particular day.

Curious to know when Friday 13th takes place? TKWeek will tell you. The app has many national and international public holidays built in, for example Reformation Day, St. Martin's Day, Christmas, Good Friday, Seven Sleepers Day, Pentecost, Ash Wednesday, Easter, International Day of Peace, and Human Rights Day. Some of the other special days TKWeek knows: Ice Saints, Valentine's Day, Mother's Day, Halloween, St. Patrick's Day, Earth Day, All Saints. And there are so many more included.

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
