The problem
Many people have multiple Google accounts — a personal Gmail, a work Google Workspace account, maybe a freelance account. Each has its own Google Calendar, and Google doesn't offer a way to sync them together. You can subscribe to other Google Calendars, but those subscriptions are read-only and refresh once a day at best.
Common issues
- Google doesn't sync calendars between different Google accounts automatically
- Subscribing to another Google Calendar's iCal feed only refreshes every 12–24 hours
- Events created in one Google account can't block time in another Google account's calendar
- Google Workspace admins may restrict calendar sharing to outside the organization
What people try
People try subscribing to their other Google Calendar via iCal URL, sharing calendars between accounts with specific permissions, or manually creating duplicate events in each account.
Why manual approaches fail
Google's iCal subscription refresh is painfully slow — up to 24 hours. Calendar sharing only works if both accounts allow external sharing (Workspace admins often disable this). Manual duplication is time-consuming and impossible to maintain reliably.
How iambusy solves this
iambusy takes the iCal feed URL from each Google Calendar account and syncs busy time between them in near real-time. Changes propagate in seconds instead of hours. No need for special sharing permissions or Workspace admin approval — just the iCal URLs you already have access to.
