I’m not aware of a year that has 13 months of 28 days? Why would you ever calculate it this way?

28*13=364. Months are different sizes so month*12 would be an over-estimate

The year has 52 weeks. 28 days is 4 weeks. 13*4=52

Because their revenue is weekly cyclical.
If they make, say, 10x more on weekdays than weekends, using a 30 day month with two extra weekdays overestimates annual revenue since it translates to a year with 264 weekdays as opposed to 260.
That's about a 1.5% increase.
28 days is 4 weeks, so you don't get fewer or more weekend days arbitrarily. Used very commonly in some industries for financial reporting and also dashboards for software engineers.
