A Shift That Spans the Bi-Weekly Period Boundary
October 23, 2026
A shift that happens to span the boundary between two bi-weekly pay periods (for example, an overnight shift that starts on the last day of one period and ends on the first day of the next) needs to be split at the boundary, with each portion counted toward its own respective pay period and workweek.

A shift runs from 10:00 PM on the last day of period 1 to 6:00 AM on the first day of period 2 — an 8-hour overnight shift, as covered in the dedicated midnight-crossing article elsewhere in this series.
- Hours before the boundary (10:00 PM to midnight): 2 hours, counted toward period 1
- Hours after the boundary (midnight to 6:00 AM): 6 hours, counted toward period 2
Why This Split Matters
Since each pay period is processed and paid separately, a shift counted entirely toward one period when it actually spans two would misstate both periods' totals — splitting at the exact boundary keeps each period's hours (and any related overtime calculation) accurate.
Frequently Asked Questions
How is a shift that spans two pay periods handled?
It's split at the boundary, with each portion counted toward its own respective pay period.
What's the split for an 8-hour overnight shift crossing the boundary at midnight?
2 hours toward the earlier period, 6 hours toward the later period, in the example given.
Why can't the whole shift just count toward one period?
Since each period is paid separately, miscounting the full shift into one period would misstate both periods' totals and any related overtime calculation.
Is this the same adjustment as a midnight-crossing shift?
It builds on that same adjustment, with the added step of also splitting the hours between the two separate pay periods.
