Why people convert ICT to ART time
- Scheduling a call from ICT to ART: a 10:00 AM start in ICT lands at 12:00 AM in ART, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -10h gap: ICT and ART 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 ART is 11:00 PM in ICT.
- Keeping family and friends in sync: knowing that 8:00 PM in ICT is 10:00 AM in ART makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a -10h gap is not.
- With a -10h gap there is no shared 9-to-5 window, so alternate the early start: one week ICT takes the early slot, the next week ART does.
