Frequently asked questions
What is the time difference between Seattle and Helsinki?
Seattle is 10 hours behind of Helsinki: UTC-7 versus UTC+3. Both figures include any daylight saving currently in force.
What is the best time to call from Seattle to Helsinki?
There is no hour that is comfortable for both. If the meeting is unavoidable, the least-bad options are the edges of each side's day — late morning in Seattle or early morning in Helsinki — and the burden should be explicit rather than assumed.
Is there any way to make Seattle–Helsinki meetings work?
Not through scheduling. With no overlap, the workable options are async written handoffs, recorded updates, or splitting coverage into two regional pods so that each pod works its own daylight hours.
