Common GeoNames IDs
| City | ID |
|---|---|
| Jerusalem | 281184 |
| Tel Aviv | 293397 |
| New York | 5128581 |
| Los Angeles | 5368361 |
| London | 2643743 |
Best Practices
- Use GeoNames IDs instead of coordinates for more reliable city-level results
- Cache API responses since Shabbat times for a given week and location rarely change
- Always include the timezone parameter (tzid) when using coordinates to avoid incorrect times
- Handle edge cases for locations near the poles where Shabbat times may be undefined
- Use the M=on parameter to include Havdalah times alongside candle lighting
Avoid
- Do not use for halachic rulings - always verify times with a local rabbi for stringent observance
- Not suitable for locations without a GeoNames ID or known coordinates
- Does not include Zmanim (halachic times of day like sunrise, sunset, chatzot) - use a dedicated Zmanim API for those
