It would be beneficial to have Christmas Eve and New Year's Eve added to the standard list of US Holidays. There are a lot of clients that I implement that request these two days. Being that they are very common holidays for most businesses, it would be beneficial to have them added to the list of current standard holidays. Rather than having to set them up as a custom holiday for clients.
I would love to see Good Friday listed as a Standard Holiday. This would eliminate us havign to go into every client every couple of years and add the next couple of years custom holidays for Good Friday.
