Can I place date pick button to right?
Should look like this:

If you’re on Valo, I think you should be able to do that quite easily by overriding .v-datefield-button styles, change
left: 1px;
to
right: 1px;
Thanks, Marcus. Solution was very close:
.v-datefield [class*="button"]
{
right: 1px;
left: auto;
border-right: 0px;
border-left: 2px solid #d8d8d8; }
(for valo)
