Cruise Port Day Planner / no guesswork hidden

Make the most of your time ashore.

Build a port-day plan around your all-aboard deadline, transport buffers, and overlapping ship calls. Keep every time and capacity assumption visible.

Before you act

Confirm whether the cruise line uses ship time or port local time. Explicit timestamp offsets determine the calculations.
Schedules, terminal assignments, tender queues, and travel times can change. Capacity is only a schedule-based proxy.
The tool does not fetch live schedules or guarantee that you will make the ship.

Your port-day timeline


Ship arrival	Sep 18, 8:00 AM EDT
Leave terminal after disembarkation	Sep 18, 8:45 AM EDT
Activity begins	Sep 18, 9:15 AM EDT
Activity ends	Sep 18, 1:15 PM EDT
Latest departure from activity	Sep 18, 3:10 PM EDT
All-aboard deadline	Sep 18, 5:00 PM EDT

Overlapping scheduled calls


No matching records. Add records or adjust your filters.

Calculation notes & limitations

Overlap uses half-open time intervals. A ship departing exactly when another arrives does not increase simultaneous capacity.

Peak capacity uses an event sweep across the imported calls, clipped to your own port window.

Plan name

Saving is optional. Files and records never leave your browser through this app.

02 / Look under the hood

The method is part of the tool.

Enter arrival and all-aboard timestamps with explicit UTC offsets. Display the resulting plan in the selected port timezone.

Subtract disembarkation, transport, activity, tender, and contingency time before judging whether the day fits.

Peak scheduled capacity counts simultaneous overlapping calls, not every ship scheduled at any time that day.

03 / Know the boundaries

Evidence before certainty.

Verify ship time, port time, all-aboard instructions, and live transport conditions directly. This tool does not guarantee a safe return.

These are reference sources, not evidence that example records have been verified. Imported records retain the source links you provide.
