Recently building a calendar control in Power Apps I wanted to show events for the selected week. Luckily it’s fairly easy to calculate thanks to the Weekday function. To calculate the start date of the week: This assumes our week starts on a Sunday, you can add which ever day you want. Saturday or Monday for example. Then to find the end of the week: So now we have the start of the week date and the end of the week date we can use these in our filter.
