Korean Standard Time (KST) is UTC+9 year-round. Eastern Time changes between EST (UTC-5) in winter and EDT (UTC-4) in summer. Consequently, the timezone gap changes seasonally: KST is 14 hours ahead of Eastern during standard time (winter) and 13 hours ahead during daylight saving time (summer). This massive flip in relative hours makes manual addition very tricky without an automated tool referencing current transition dates.
Compare standard business hours and overlaps between KST and EST.
