•The Time Gap Between San Francisco and Bangalore
San Francisco runs at UTC-8 in January and UTC-7 in July, shifting its clocks for Daylight Saving Time.
Bangalore runs at a fixed UTC+5:30 year-round, with no Daylight Saving Time.
Because only San Francisco observes Daylight Saving Time, the gap changes every time its clocks do: it runs 12.5 hours for roughly 8 months of the year and 13.5 hours for the other 4. Any recurring meeting between these two needs to be checked twice a year, not set once and forgotten.
Realistic Overlap for a Standard 9-to-5
Assuming a standard 9am–5pm workday on both ends, San Francisco and Bangalore share no true overlap. There's no window where both teams are in a standard workday at the same time, so this pairing needs to run async by default, with any live call landing outside someone's normal hours.
- January: the one-hour slot that splits the inconvenience most evenly is 5:30pm in San Francisco = 7:00am in Bangalore (next day).
- July: the one-hour slot that splits the inconvenience most evenly is 6:00pm in San Francisco = 6:30am in Bangalore (next day).

PST to IST: What the Abbreviations Mean
PST — Pacific Standard Time (PST, UTC-8) runs part of the year; the rest of the year the same clocks are on Pacific Daylight Time (PDT, UTC-7) instead. People casually say "PST" for both — the scrubber above already resolves whichever one is actually in effect for the date you pick.
IST — India Standard Time (IST) is fixed at UTC+5:30 year-round — it does not observe Daylight Saving Time.
Timezone abbreviations aren't globally unique — several regions reuse the same three or four letters for unrelated zones. The scrubber is anchored to IANA timezone data (America/Los_Angeles and Asia/Kolkata) rather than the abbreviation text, so there's no ambiguity in the actual conversion.
