How the calculations work
Time zones
We use the IANA time zone database through PHP's native date library and Carbon, so daylight-saving transitions and historical offsets are handled by the same rules your operating system uses.
Holidays
Public holidays come from curated country rules. Where a country publishes regional calendars, the tool keeps those rule sets separate instead of flattening them into one list.
Sun and Moon
Solar and lunar positions are computed locally with well-known astronomical formulas. No location data is sent to a third party to render sunrise, sunset, or the moon's compass position.
