When is the best time to call Phoenix from Delhi?

There is no time inside normal working hours in both cities, so someone has to take the call outside them. The nearest workable windows are listed above — pick one and alternate who gets the awkward slot.

Does Delhi observe daylight saving time?

Does Phoenix observe daylight saving time?

No. Phoenix stays on UTC-7 all year, so its clocks never move.

If it is midday in Delhi, what time is it in Phoenix?

It is 23:30 in Phoenix, still on the previous day. That holds for the current offsets; it does not change through the year, because neither city moves its clocks.

Which time zones do Delhi and Phoenix use?

Delhi uses Asia/Kolkata, currently UTC+5:30 (IST), and Phoenix uses America/Phoenix, currently UTC-7 (MST). Those identifiers are the ones to use in code — abbreviations are ambiguous and offsets change.
