Why people convert CDT to ART time
- Scheduling a call from CDT to ART: a 10:00 AM start in CDT lands at 12:00 PM in ART, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both CDT and ART are inside the 9-to-5 working day between 9:00 AM and 3:00 PM CDT time (11:00 AM–5:00 PM ART). That is roughly 6 hours of usable overlap.
- Coordinating a CDT-based team with ART 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 CDT" is unambiguous; "3 PM" across a +2h gap is not.
- Block 9:00 AM–3:00 PM CDT as the recurring meeting window if you work primarily from CDT and need ART colleagues present.
