Calculate movie end times from start time and runtime, including theater trailers, credits, exit buffers, or at-home pauses for schedule planning.

Enter the start clock time and movie runtime. The result identifies any finish after midnight.

Use a 24-hour clock, for example 19:30 for 7:30 PM.

Use a positive whole-minute duration; 2.25 hours equals 135 minutes. Unit changes preserve the duration.
