Civil twilight is the period when the sun is within 6 degrees below the horizon — bright enough to see outdoors without lights, and what people usually mean by “it gets light” and “it gets dark”. Nautical uses 12 degrees and astronomical 18 degrees. At high latitudes a band can be absent for a whole day, in which case the row is left blank.

Computed from the coordinates of Arrah: 25.55629, 84.66335.
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 Arrah, ticking in the Asia/Kolkata 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
Arrah is bound to the IANA identifier Asia/Kolkata. 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 Arrah use right now?
- Arrah uses the IANA time-zone identifier Asia/Kolkata, with a current UTC offset of UTC+05:30. 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 Arrah observe daylight saving, and what changes by date?
- Whether Arrah observes daylight saving depends on the rules for Asia/Kolkata. 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 Arrah?
- Yes. The server provides an initial page value, then the browser immediately recalculates the current moment for Asia/Kolkata, 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.
