Ninety minutes apart
Oman keeps UTC+4 all year and India keeps UTC+5:30, so the gap never moves: 09:00 in Muscat is 10:30 in India, and a send scheduled for 10:00 IST lands at 08:30 in Ruwi or Qurum. One shift in India covers almost the whole Muscat working day.
That closeness changes how the 24-hour service window feels. A buyer who writes at 16:00 in Muscat reaches your team at 17:30 IST, before most Indian offices close, and a reply the same evening keeps the conversation free-form. There is no night shift to plan for.
What needs planning is consent. Oman's Personal Data Protection Law asks for the data subject's written consent before any advertising or marketing material is sent, so a Muscat promotion needs more than a ticked box. The Oman guide walks through what that means for WhatsApp.
