Why people convert AST to Romania time
- Scheduling a call from AST to Romania: a 10:00 AM start in AST lands at 5:00 PM in Romania, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both AST and Romania are inside the 9-to-5 working day between 9:00 AM and 10:00 AM AST time (4:00 PM–5:00 PM EEST). That is roughly 1 hours of usable overlap.
- Coordinating a AST-based team with Romania 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 AST" is unambiguous; "3 PM" across a +7h gap is not.
- Block 9:00 AM–10:00 AM AST as the recurring meeting window if you work primarily from AST and need Romania colleagues present.
- Romania: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
