Calendar App to keep track of shared custody ?

My girlfriend's kids are in a shared custody, and I'm having a hard time keeping track of when they're at their dad's (the agreed schedule is pretty convoluted). I'd like a calendar that could keep track of my normal schedule, but could also, for instance, color the dates certain colors depending on where the kids are that day. Or any other such system.Bonus points if it can also pull events and deadlines from work too so I can centralize, but I can live without. Super bonus points if it is accessible from my computer, but it's more important that it be accessible from my phone.Right now I'm stuck with creating "all-day" events on Google Calendar, which clutters my views and isn't even accurate since most days the kids are with their dad only during the morning or the evening, not the whole day...Would someone have something to recommend ?Thank you all ! via /r/Parenting https://ift.tt/2OFYKA4
