TKWeek

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.
