FAQ
›How do defaults work?
We use your browser zone (fallback UTC). In Turkish locale, Europe/Istanbul is preselected.
›Do you handle daylight saving?
Yes. Offsets come from the built-in Intl API which applies current DST rules.
›Can I compare more than two cities?
Yes. Add up to five destinations to see the same instant across all of them.
›What are working-hour overlays?
We shade 09:00–18:00 in each zone to spot overlapping work time quickly.
›Is this offline?
All calculations happen locally without remote API calls.
