What is Timetastic Calendar Insights?
Timetastic Calendar Insights shows how quickly major calendar apps refresh subscribed calendar feeds, based on real-world feed checks collected by Timetastic. It compares the freshness of calendar sync across Apple Calendar, Google Calendar, Microsoft Exchange, and Microsoft Outlook, using median refresh gaps over recent traffic.
The tool focuses on one question: which calendar app keeps you most up to date? It presents live tracking over the last 14 days, league-table style rankings, and app-specific averages so you can see how stale a subscribed calendar may become. Timetastic says it serves over a million calendar feeds every month, which is the data source behind the dashboard.
It is aimed at people who rely on subscribed leave calendars and want to understand how often different calendar clients re-fetch those feeds. That makes it useful for admins, team leads, and employees who use Timetastic calendar feeds to follow team time off, departmental leave, or whole-organisation calendars.
The site also explains how the data is measured and why it should be treated as a strong guide rather than exact truth. It only records the timing of feed fetches, not personal data or event content, and the results are aggregated and anonymised.
Overall, it is less a scheduling tool and more an analytics dashboard for calendar feed refresh behavior. It helps teams set expectations about sync delays when using Google, Apple, or Microsoft calendar clients with Timetastic feeds.

Frequently asked questions about Timetastic Calendar Insights
What does Timetastic Calendar Insights measure?
It measures how often calendar apps re-fetch subscribed Timetastic calendar feeds, so you can see how quickly those calendars refresh in practice. Timetastic says the dashboard compares the freshness of Apple Calendar, Google Calendar, Microsoft Exchange, and Microsoft Outlook using real fetch activity from its feed traffic.
Which calendar apps are included?
The page specifically highlights Apple Calendar, Google Calendar, Microsoft Exchange, and Microsoft Outlook. It also breaks out Apple Calendar on iPhone, iPad, and Mac, Google’s calendar importer, and Microsoft variants used in Outlook on the web, Microsoft 365, and the Windows desktop app.
How fresh is the data?
The dashboard is labeled as live and based on the last 14 days for the main charts. Timetastic also says the ranking uses the median gap per app over the last 30 days so that a few unusually slow checks do not distort the picture.
How does Timetastic collect this information?
Timetastic says it watches when calendar apps fetch subscribed feeds and records the moment each fetch happens. It then uses the gap between fetches to estimate how long a calendar could be out of date.
Does the site store personal calendar content?
No. Timetastic says it only counts when calendar apps fetch feeds and never looks at who you are, who is in your calendar, or what any event says. The page says no personal data or calendar content is read, stored, or shown.
What kinds of Timetastic calendars are shared as feeds?
The page shows five feed types: Full Organisation, My Calendar, My Department, My Favourites, and My Team. It also shows which of those are most commonly shared, with Full Organisation being the most popular.
Why might my calendar look outdated?
The site explains that the calendar app itself decides when to re-fetch a subscribed feed, so some apps update more slowly than others. That means a leave calendar can remain stale for several hours depending on the client being used.
Who is this dashboard for?
It is for teams that subscribe to Timetastic leave calendars and want to understand sync behavior across different calendar apps. That includes employees checking their own team’s time off and admins who need to set expectations about calendar freshness.
Is this a scheduling or leave-booking tool?
No. The page is an analytics view about calendar sync speed, while Timetastic itself is the leave-planning system that powers the feeds behind the dashboard.
How should the results be interpreted?
Timetastic says the figures are a very good guide, not gospel, because the dashboard sees a large slice of real-world traffic but not all of it. The results are aggregated, anonymized, and designed to show typical refresh behavior rather than exact guarantees.
