Hi! I am trying to change what day of week the DateTimeInput calendar popup starts with. Here in Sweden we really like to start with Monday instead of Sunday. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/7/4728f2ef9a723a5718bb114777aa1f2775850ad9.png) I cant figure out how to do this. ---

A fellow countryman asked this question before. The answer is that the component doesn't support it but some magic can be applied and Victor supplied an answer that seemed to work. > [@Datetime picker - change first day of the week?](https://forum.inductiveautomation.com/t/datetime-picker-change-first-day-of-the-week/57353/1): > > Is there a way to change the first day of the week for the datetime picker in perspective? In Sweden it’s unsusal to put Sunday as the first day of the week and I can’t seem to find a way to change it. ---

Pascal just mentioned this in one of his posts yesterday: > [@\[FEATURE\] Allow styling dates in the datetime picker calendar component](https://forum.inductiveautomation.com/t/feature-allow-styling-dates-in-the-datetime-picker-calendar-component/79132/2): > > I'd also like to see more customization options for the date components, notably the possibility to change the starting day of rows - weeks go from Monday to Sunday in France, having rows start with Sunday can be a bit counter-intuitive. Maybe the possibility to select a full week too ? As always, there are ways of doing this as is. But frankly it's not worth the time it takes to get good results, for example you could change the grid-area to make rows start with Monday, but then you end up w… ---

It's far from perfect. Things tend to get out of place quickly. For example, the previous/next month days used to fill the empty spaces are still there, so you get lines with only useless days AND empty spaces, and when it creates a new line the popup doesn't scale. I'd rather keep Sunday-starting rows than mess the whole thing up. I guess it's all fixable, but frankly it gets way too messy and complicated just for this.
