Why people convert Romania to CST time
- Scheduling a call from Romania to CST: a 10:00 AM start in Romania lands at 1:00 AM in CST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: Romania and CST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in CST is 12:00 AM in Romania.
- Coordinating a Romania-based team with CST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM EEST" is unambiguous; "3 PM" across a -9h gap is not.
- With a -9h gap there is no shared 9-to-5 window, so alternate the early start: one week Romania takes the early slot, the next week CST does.
- Romania: Clocks fall back on Sun, Oct 25, 2026. Re-check this page after that date because the offset changes and so does the -9h gap.
About EET (Eastern European Time)
Eastern European Time (EET) covers a wide geographical area including Eastern Europe (Finland, Greece, Romania, Bulgaria, Ukraine), the Middle East (Israel, Lebanon, Jordan), and northeastern Africa (Egypt, Libya). During summer, most EET countries switch to Eastern European Summer Time (EEST, UTC+03:00). Turkey permanently moved to UTC+03:00 in 2016, effectively leaving EET.
About CST (Central Standard Time)

CST is also used in Mexico City and much of Central America including Guatemala, Honduras, El Salvador, and Costa Rica. During summer, most of the US and Canada switch to Central Daylight Time (CDT, UTC-05:00), while Mexico and Central American countries generally remain on CST.
