What time-zone overlap can I expect from India?

Real overlap is 4-6 hours per day between IST (India Standard Time, UTC+5:30) and AEST (Australian Eastern Standard Time, UTC+10), or AEDT (UTC+11) during daylight saving. Specifically: 1 PM, 7 PM IST = 5:30 PM, 11:30 PM AEST (your business afternoon / early evening, our late afternoon / evening). We schedule daily stand-ups, calls, screen-shares in this window. For early-morning Sydney calls (8-10 AM AEST = 3:30-5:30 AM IST), we offer that on launch nights or for critical incidents. Async tools we use: Loom for code walkthroughs, written end-of-day status notes (sent before our 7 PM IST = your 11:30 PM AEST), Notion project board kept current. WA / NT (UTC+8) overlap is 2 hours longer; SA / NT during AEST is similar to east-coast.
