⚠️ Note: 2026-07-05 is not a normal workday in one or both regions based on their configured calendar. The overlap below should be treated as a reference, not a guaranteed office-hours window.
⚠️ There is no clean same-day business-hours overlap on 2026-07-05. A practical compromise is around 11:00 PM PET, which reaches 9:30 AM IST near the start of their workday.
- DST Safety: Neither PET nor IST uses Daylight Saving Time in our dataset, making business-hour relationships stable year-round.
- Lima Stock Exchange (BVL): 09:00-15:00 local time in Lima.

Frequently Asked Questions
What is the time difference between PET and IST?
During standard time, Indian Standard Time is 10.5 hours ahead of Peru Time.
Does Peru observe Daylight Saving Time?
Peru does not observe Daylight Saving Time and has not done so since 1994. PET remains fixed at UTC-05:00 throughout the entire year, with no seasonal clock changes affecting business hours, market schedules, or international coordination.
How does Peru Time (PET) align with the US?
PET (UTC-05:00) is identical to US Eastern Standard Time (EST) during the Northern Hemisphere winter — Lima and New York run on the exact same clock. When the US shifts to Eastern Daylight Time (EDT, UTC-04:00) in summer, PET falls one hour behind, but a full shared workday between Peru and the US East Coast remains entirely achievable without scheduling concessions on either side.
Does India observe Daylight Saving Time (DST)?
India does not observe Daylight Saving Time and has not done so since 1945. IST remains fixed at UTC+5:30 every day of the year, meaning the offset between India and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Why does IST have a 30-minute offset?
India chose the 82.5° East meridian — which passes through Mirzapur in Uttar Pradesh — as its central reference longitude, as it bisects the subcontinent geographically. That meridian sits exactly 5 hours and 30 minutes ahead of the Prime Meridian in Greenwich, producing the UTC+5:30 offset that has defined IST since 1906.
