How many patterns can be compared at once?

Up to three side by side, each with its own independently checked set of working days.

Can a pattern skip a middle day of its own week, not just weekend days?

Yes, any combination of days can be checked or unchecked independently, so a pattern that works every day except one specific midweek day is entirely possible.

Worked example

A Monday-through-Friday workweek gives 5 working days in any Monday-to-Sunday range, the familiar pattern most schedules assume by default. A Sunday-through-Thursday workweek, common in some regions, also gives exactly 5 working days over that same range, but on entirely different specific dates, which matters directly when comparing a shared deadline or schedule across teams that follow different regional conventions.

Common mistakes

Assuming every region follows the same Monday-through-Friday convention. Several regions run a Sunday-through-Thursday workweek instead, with Friday and Saturday as the days off.
Comparing two patterns' working-day counts without checking which specific dates they land on. Two patterns can total the same number of days while covering different parts of the week entirely.

Limitations

This compares workweek patterns only, without any holiday exclusions applied. See the Holiday Impact Calculator separately to add regional holidays on top of a pattern.
