Thanks but that's not exactly what I want. You know how Google docs works? For example DP and I have a shared budget. He can change his outgoings on it, I change mine and we can both see how much the family outgoings are. I basically want something like that but a calendar.
Its not for work so thats why I dont want it in outlook because I don't have that at home. I bet there's a phone app for it!
Google calendar is great at sharing. You have personal calendar and can have others as well, so can have a calendar for each child. Then you grant access rights to other people, so they can view, create events etc.
There are various apps to use with Google calendar. I think it uses the ical format. I have apps on android and ios to access google calendar. Sometimes I find it easier creating an event from the google calendar website, particularly if it is an event that auto repeats. Expect the apps will so it, i just have not learnt how.
