Syncing Many Calendars Among iOS Devices, Mac, Windows PCs


There is definitely a convenience in having

your calendars

always in your pocket thanks to your iPhone or iPod Touch. And now with Apple’s iCloud service it is also possible to have all of them synced seamlessly at all times and across all your devices.

However, not everyone knows how to enable iCloud and thus, end up updating their calendars on all their devices or even worse, end up relying entirely on one device only.

Of course, in the past those of you who managed their calendars across multiple devices usually did so by using solutions like CalDAV and online services like Google Calendar. Thankfully, the iPhone also provides support for such services in a seamless way, making it deal for both newbies and seasoned calendar users.

That said, let’s take a look at how to sync one or more calendars across all iOS devices, as well as across Macs and Windows PCs using both iCloud and CalDAV.

Note: Since there are different CalDAV clients with very unique characteristics that can help you set the service up on your Windows PC, I won’t mention any specific one here. A simple web search will direct you to all of them.

On Your iOS Device
