Computed from the coordinates of San José del Castillo: 20.51405, -103.23796.
Sunrise and sunset are the moments when the centre of the sun is 50 arcminutes below the horizon, which accounts for atmospheric refraction and the sun’s apparent radius — the same convention as common astronomical almanacs. Daylight is sunset minus sunrise; night is taken as 24 hours minus daylight. Elevation, terrain and local weather are not included, so observed times can differ by a minute or two.

How to use this page
The top of the page shows the current date and time in San José del Castillo, ticking in the America/Mexico_City zone. To convert a specific moment to another city, use the comparison link below, where you can enter a date and time.
How the time is calculated
San José del Castillo is bound to the IANA identifier America/Mexico_City. The server resolves the UTC offset and daylight saving state for the requested moment and renders the first view; the browser then keeps time in the same zone and re-syncs when the tab comes back to the foreground. No fixed offset stands in for the zone, and no zone is guessed from the city name.
FAQ
- Which time zone and UTC offset does San José del Castillo use right now?
- San José del Castillo uses the IANA time-zone identifier America/Mexico_City, with a current UTC offset of UTC-06:00. That identifier represents date-based rules rather than one permanent hour difference; daylight saving can make offsets vary across dates. Keep the requested date when converting historical or future times. This page applies the city’s time-zone rules and shows the matching local date alongside its clock reading.
- Does San José del Castillo observe daylight saving, and what changes by date?
- Whether San José del Castillo observes daylight saving depends on the rules for America/Mexico_City. The page shows the current status and lists the local time of a transition when one occurs; a year can have 0, 1, or 2 changes. Specify the date when checking a historical or future time, because today’s UTC offset cannot stand in for another date’s rule. Local clock changes can differ across time zones.
- Does the cached time page show the current time for San José del Castillo?
- Yes. The server provides an initial page value, then the browser immediately recalculates the current moment for America/Mexico_City, refreshes the display every 1 second in 24-hour format, and continues the clock; it resynchronizes when you return to the tab. Cached HTML does not leave the clock frozen at its generation time. The offset still follows the selected date’s zone rules, and a webpage clock is not a precision time-synchronization instrument.
