Powershell Golf: Next business day

powershell

Solution

This is pretty short too (but uses aliases):

,(1,2-eq7-(date).dayofweek)|%{(date)+"$(1+$_[0])"}

In one single statement:

(date)+"$(1+$(@(1,2-eq7-(date).dayofweek)))"

A few notes about this approach:

In Powershell (v1 at least), comparisons with collections return items where the condition is true, for example:

`PS> 1,2 -eq 1` `PS> 1`

I'm taking advantage of the fact that the actual exceptions to the rule `today + 1` to calculate the next business day are only Friday (+3 days) and Saturday (+2 days).
