Hey Product Hunt! 👋
I'm Gökhan, the maker of Inday.
I built this because I kept running into the same problem: every project involving scheduling, HR, or finance needed holiday data — and there was no simple, affordable API for it.
Inday solves that. One API call, accurate public holiday data for 100+ countries.
I'd love your feedback:
• Which countries or features matter most to you?
• Is the free tier (1,000 req/month) enough to get started?
• Anything missing from the docs?
Happy to answer any questions! 🙌
Congrats on the launch, Gökhan! 🚀 As a backend developer working with PHP/Symfony, I constantly deal with scheduling and date calculations for e-commerce and ERP integrations. Having a reliable, developer-friendly holiday API like Inday would save so much time instead of maintaining custom holiday tables per country. The working days calculation endpoint is a killer feature — super useful for delivery date estimations and SLA tracking. Great work, looking forward to seeing it grow!
I've been using this for some experimental side projects and loving it so far. Now thinking about integrating it into the commercial products i'm working on with a premium plan. With this i'll have one less thing to worry about while writing code. Thanks for sharing this with us devs guys!
