Question

How to calculate next and previous business days in Rails?

Answer 1

Well, you can use something like yesterday = 1.days.ago to get yesterday's date. Use yesterday.strftime('%w') to get the day of the week as a integer (0=Sunday, 6=Saturday). If yesterday is 0 (Sunday), then the previous day of the week would be 3.days.ago ... you get the idea.

And you can use tomorrow = 1.days.since to get tomorrow's date.
