Great module @BKeyport , thanks a lot! I changed my custom.css a bit to match my other modules and ended up with a rather minimalist look:

Here’s the css if anyone’s interested:
.MMM-Multimonth .month {
padding-left: 0px;
padding-right: 0px;
}
.MMM-Multimonth .month-header {
background-color: #000000;
text-transform: uppercase;
font-size: 15px;
font-family: "Roboto Condensed", Arial, Helvetica, sans-serif;
font-weight: 400;
border-bottom: 1px solid #666;
line-height: 15px;
padding-bottom: 5px;
margin-bottom: 10px;
color: #999;
border-radius: 0px;
}
.MMM-Multimonth .days-header {
color: #808080;
text-align: center;
}
.MMM-Multimonth .weeknumber:before {
content: "v. ";
}
.MMM-Multimonth .weeknumber {
background-color: #000000;
color: #808080;
padding-right: 9px;
}
.MMM-Multimonth .day {
text-align: center;
}
.MMM-Multimonth .current_day {
background-color: #FFD11C;
text-align: center;
border-radius: 4px;
padding-left: 0px;
padding-right: 0px;
margin-left: 4px;
margin-right: 4px;
}
