Common uses
- Schedule international meetings and webinars.
- Plan calls with remote colleagues or clients.
- Check flight arrival times.
Tips for best results
- Daylight saving dates differ between the US, Europe and the southern hemisphere – always check the date.
How time zones and daylight saving work
There are more than 38 local time offsets in use, including half-hour and 45-minute zones such as India (UTC+05:30) and Nepal (UTC+05:45). Daylight saving is observed in North America, most of Europe and parts of Australia and South America – on different dates – while most of Asia and Africa do not change clocks.
Tips for international scheduling
Choose cities rather than abbreviations, because “CST” can mean US Central, China or Cuba Standard Time. Note when Europe and the US change clocks on different weekends in March and October/November: for a week or two the usual gap between London and New York shrinks by an hour.
