Year CSV09:00 EST to CDT throughout 2026
09:00 in EST converts to 09:00 in CDT on every date in 2026. The destination has the same calendar date.
Every calendar date is included, not just workdays. Date ranges include both endpoints. Based on IANA 2026e; future rules may change.
DON’T LOSE A DAY
When does EST time become a different date in CDT?
Your complete source day: 2026-11-10. Each range shows which destination date to use.
EST · 2026-11-1000:00–24:00UTC−05:00
CDT · 2026-11-1000:00–24:00UTC−05:00 Same date
Range starts are included; ends are excluded. 24:00 means midnight at the end of that date. Repeated hours appear separately with their UTC offsets. The strip is proportional to elapsed time.
