Calendars

**Warning**
Not all Calendar clients allow real-time sync

Make sure to use a calendar app that allows real-time sync. This is typically not a problem for things like Rent Expirations and option periods, but as you start building out events and notebook tasks the delay can cause confusion.

Client	Typical Delay	Can force refresh
Outlook Desktop	15 min	yes
Thunderbird	15 min	yes
Google Calendar	8 hours	no
Outlook online	15 min	no
Apple Calendar	8 hours	no
