Different companies will anchor the week to start on Sunday, Monday, or other days of the week. When filtering and displaying data, Kapiche defaults to Sunday as the week start day, but this can be overridden when creating a Project or updating its settings.

A Smart Report can use a different week start from its project. Click Edit mode, then Configure. Under Date settings, set First day of week. Project default (<day>) uses the project's setting. Weekly ranges and weekly charts in that report then start on the day you choose. Click Save.
