Why time zone overlap matters for remote work
On a fully remote team, the difference between three hours of overlap and one hour of overlap is the difference between getting unblocked the same day and waiting until tomorrow. Even async first companies usually agree on a "core" window where everyone is reachable for live calls, pair work, and quick decisions.
This calculator is meant for that conversation. Use it when you are scoping a new role, joining a globally distributed team, or scheduling a recurring meeting that has to land at a fair hour for the whole group. It is also useful when you are deciding whether to apply to a job that lists "must overlap with Pacific Time" or similar restrictions.
