Editor's Overview

TKWeek is a calendar & agenda application developed by Thomas Künneth, packaged as a single Android APK of version 2.3 weighing in at 4.34 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 4.34 MB, so it installs quickly even on modest connections.
This build is signed by "Thomas Künneth" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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.

Frequently Asked Questions

Is TKWeek free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does TKWeek require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is TKWeek safe to install?
We link to the exact APK published by Thomas Künneth. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update TKWeek?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
