If you ever fought, this might help.
Here’s a DEV write-up on a public world time API that needs no sign-ups or API keys, and it’s frontend-friendly via CORS.
What I liked:
- Timezone + DST handled
- Geo-IP endpoint to detect the user timezone
- quick start examples
Read it here: get time by timezone https://dev.to/time-now-api/i-built-a-free-open-world-time-api-no-api-keys-cors-enabled-5en
If you’re building frontend countdowns. Cheers.
