The editorial policy of Kalinga Times is to check every offset and daylight-saving date against the IANA time zone database, state the source and check date on each page, and show the calculation behind every tool.
Sources we use
- IANA time zone database (tz database), the standard source for time zone and daylight-saving rules.
- Official notices from governments when a country changes its time zone or daylight-saving rules.
- For India: Indian Standard Time is UTC+5:30, kept by the CSIR–National Physical Laboratory, New Delhi.
What the tools calculate
The converter takes a date and time in one zone, applies the offset that zone uses on that date, and shows the result in the other zone. For dates near a clock change, the page shows which offset applies.
Review
Every page is reviewed at least every 180 days, and sooner when a reader reports an error or a source changes.

FAQ
Why does IST to EST change during the year?
India does not change its clocks, but the US eastern zone switches between EST (UTC−5) and EDT (UTC−4), so the gap is 10 h 30 min or 9 h 30 min.
How often are pages reviewed?
At least every 180 days, or sooner after a report or a rule change.
