Can I code this? A Timezone Meeting Finder for Remote Teams
Show each teammate's working hours on one shared timeline and highlight where they overlap — genuinely simple once you're honest that pure display, not calendar sync, is the actual goal.
Build it
Effort: an eveningRunning cost: $0/mo to start
Why CanICodeThis says Build it
Displaying multiple timezones on a shared horizontal timeline is well-documented date/time-library work
Highlighting overlapping working-hours windows across everyone is a straightforward range-intersection calculation
Saving a team's members and their timezones is simple CRUD
The parts that'll cause problems
Syncing with everyone's actual calendars (not just their general working hours) reintroduces real calendar-integration complexity
Daylight saving time transitions need careful, well-tested date-library handling to avoid off-by-one-hour bugs
Suggesting an optimal meeting time automatically (not just showing overlap) is a small but real additional feature

The build prompt
Build me a timezone overlap finder: add team members with their timezone and typical working hours, show everyone on one shared horizontal timeline, and highlight the windows where everyone's hours overlap. Use a well-tested date/timezone library — don't hand-roll DST handling. SQLite behind a small API.
