The next leap day won’t show up for another four years. So, if you have some sort of business dealing for which you’d prefer not to notice anniversaries, do it today. You won’t have to worry about it for another four years!
Seriously, though, the leap year does have an effect on business. If you work in a salaried job, you might have noticed a small change in your pay. If you get paid every two weeks, your salary is usually divided by 26. However, this year, it will be divided by 27 to make up for the extra day. On the flip side, you may end up with another pay period for the year.
