Why Subscribed Calendars Stop Updating (And Why It Isn’t Your Fault)
Most developers who work with calendars eventually hit the same strange bug. Someone subscribes to your ICS feed. Everything looks fine. Then a day or two later nothing updates. Events go missing. Times drift. Outlook users swear the feed is frozen. Google polls whenever it feels like it. Apple refreshes until it doesn’t. You debug your code. You check the ICS. You regenerate the file. You...
Why Google Calendar Sometimes Ignores ICS Updates (and What Developers Can Do About It)
If you have ever sent calendar invites from your own backend, you have probably seen this problem: You send an event update The ICS file validates Google Calendar imports it without errors Nothing changes No error. No warning. The update simply does not apply. This is one of the most common issues developers face when working with ICS. The root cause is that Google interprets the specification...
Getting Synara ready for launch & solving the last hard problems before we ship
Hey everyone, here's a quick update on Synara, my API for delivering calendar invites that don’t break across Google, Outlook, Apple, and ICS. We’re finally getting close to launch, and I wanted to share where things stand and what’s left. Where we're at Over the last few weeks, I’ve been tightening the fundamentals: Google Calendar sync is done Real two-way updates, no hacks, no scraping, no...
ICS isn’t the only problem - vendor APIs are the real mess. That’s why I’m building Synara.
When I wrote my last post about ICS being 25 years old, a bunch of people asked the same thing: “Why not just use Google Calendar API, Outlook Graph, Apple Calendar, etc.?” Because that’s where the actual pain is. If you’ve ever tried to build anything around scheduling, you already know how bad it gets: Google does things one way Microsoft does things another Apple doesn’t even give you a...
ICS Is 25 Years Old. Here’s Why I Built Synara to Replace It for Developers
If you’ve ever tried to send calendar invites or event updates from your app, you’ve probably discovered the same thing I did: ICS is really old, inconsistent, and every provider interprets it differently. Google, Microsoft, and Apple all parse ICS with their own quirks. That means: Updates get ignored or duplicated Recurring rules behave differently RSVPs are unreliable across clients...
