Time Zone Converter for Remote Work & International Meetings
With remote teams spread across the US, UK, Australia, and New Zealand, scheduling meetings across time zones is a daily challenge. The US Eastern time zone is typically 5 hours behind UTC (4 hours during EDST); Sydney is UTC+10 (UTC+11 during AEDT); Auckland is UTC+12 (UTC+13 during NZDT).
Daylight Saving Time makes conversions more complex: the US, UK, and Australia all observe DST but on different schedules. During March–November the US is on EDT; the UK switches to BST from late March to late October; Australia switches in October–April (Southern Hemisphere summer). This converter accounts for current DST automatically.
