First day of a month as start of week

Hello @rahul.kolage,

Welcome to the QuickSight community! Thanks for your question.

You can use calculated fields to adjust the start day of the week. They will all take a similar form, you just adjust the numerical value in the calculation depending on what day you want to start your week.

Some examples can be found here :

Or you can also create a sample in our QuickSight Arena and we will be able to help you with the calculation.
