How to use the Shift Handover Calculator

  1. Enter outgoing shift end and incoming shift start.
  2. Review the values before calculating, especially that both timestamps use the same date and time zone.
  3. Select Calculate to measure either an overlap available for handover or a coverage gap between shifts.
  4. Correct the inputs if the result looks unexpected; a common source of error is interpreting a positive gap as handover time when it actually means no simultaneous coverage.

What this calculator does

Measure whether two shifts overlap for handover or leave an uncovered gap. The calculator uses outgoing shift end and incoming shift start to measure either an overlap available for handover or a coverage gap between shifts.

Date and planning results use the weekend, holiday, schedule and time assumptions entered on the page. Confirm organization-specific calendars before relying on a deadline or roster date.

Difference = incoming shift start - outgoing shift end.

An overlap and a coverage gap are opposite results

If the incoming shift starts before the outgoing shift ends, the difference is available handover overlap. If it starts after the outgoing shift ends, the same difference becomes an uncovered gap. Confirm both times refer to the intended day before interpreting the sign.

Calculation example

Example input: Outgoing shift ends 6:00 PM; incoming shift starts 5:45 PM

Example result: 15-minute handover overlap.

Your result will change with outgoing shift end and incoming shift start; check that both timestamps use the same date and time zone before comparing it with another system.

How to interpret the result

The most important verification point is that both timestamps use the same date and time zone. Also check for interpreting a positive gap as handover time when it actually means no simultaneous coverage before using the result in payroll, scheduling, staffing or reporting.

Practical checks before using the result

  • Verify the key assumption: that both timestamps use the same date and time zone.
  • Avoid a common error: interpreting a positive gap as handover time when it actually means no simultaneous coverage.

Calculation design and testing notes are documented in the Calculator Methodology and Accuracy Policy.
