Calendar Sync Insights

Which calendar app keeps you most up to date?

Timetastic serves over a million calendar feeds every month. Every time Google, Apple or Microsoft re-checks one, we see it, so we can show how fast they really refresh the calendars you subscribe to.

What people share

The calendars teams subscribe to

Of the feeds we serve, whole-organisation calendars are the most popular.

How we know this

Timetastic lets people subscribe to their team's time-off as a calendar feed. Calendar apps (Google, Apple, Microsoft and others) re-fetch those feeds on their own schedule, and we record the moment each fetch happens.

The gap between two fetches is how long your calendar could be out of date. We take the median gap per app over the last 30 days, so a few stragglers don't skew the picture. We see a large slice of real-world traffic, but not all of it, so treat this as a very good guide, not gospel.

Anonymised & aggregated

We only count when calendar apps fetch feeds. We never look at who you are, who's in your calendar, or what any event says. No personal data or calendar content is read, stored, or shown here. Everything on this page is an aggregate.

Made by the team behind Timetastic

Timetastic is the simple way for teams to book and track time off, and it's what powers the calendar feeds behind this dashboard. Give your team a calendar that's always up to date.
