Why people convert Saudi Arabia to UTC time
- Scheduling a call from Saudi Arabia to UTC: a 10:00 AM start in Saudi Arabia lands at 7:00 AM in UTC, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Saudi Arabia and UTC are inside the 9-to-5 working day between 12:00 PM and 5:00 PM AST time (9:00 AM–2:00 PM UTC). That is roughly 5 hours of usable overlap.
- Coordinating a Saudi Arabia-based team with UTC 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 -3h gap is not.
- Block 12:00 PM–5:00 PM AST as the recurring meeting window if you work primarily from Saudi Arabia and need UTC colleagues present.
About AST (Arabia Standard Time)

About UTC (Coordinated Universal Time)
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation.
