Description
A world clock for Windows made for working with people in other time zones. Add the cities you work with and see them side by side. Type a time or scroll over any clock and every city converts at once. The meeting planner shows the hours when everyone is inside working hours, and there's a live day and night map. Free and open source (MIT), no ads, no account, and the app sends nothing anywhere. On the Microsoft Store, or try the real app in your browser first.
