Mountain Time is UTC−7 in winter and UTC−6 from the second Sunday in March to the first Sunday in November; India stays at UTC+5:30. A Denver working day from 08:00 to 17:00 therefore runs from 19:30 to 04:30 IST in summer and from 20:30 to 05:30 IST in winter.
An Indian team rarely covers that with one shift. An evening shift catches the Denver morning; the morning shift in India answers what arrived during the Denver afternoon, still inside the 24-hour window. What falls between them is left to systems, which send utility templates for every booking, ticket or order change.
Plan the handover on the inbox, not on chat groups: labels for what is waiting, private notes for what was promised, and transfers when the evening shift hands a thread to the morning.
