Interesting idea, but needs more work.<p>Scanning the list of countries: Presenting them alphabetically and vertically, instead of left-to-right, makes much easier scan-ability. Some countries were also out-of-place alphabetically, e.g. Spain.<p>No countries with a Friday-Saturday weekend seemed to be present, for example Bangladesh. Knowing the days of the weekend is really useful and really related to needing to know public holidays (and I imagine a pretty quick-kill as it only needs to be input once per country).<p>I checked public holidays for where I am currently: China. It's wrong. National week (October 1st to October 7th) is 7 days, not one day, today's the last day. But the preceding Saturday and Sunday were working days (i.e. there was a 7 day working week before the 7 day national week of holiday, displaced weekend).<p>This seems valuable. But only if accurate and covers everywhere. Which it isn't now.<p>I also have an accurate list of international holidays (including weekends) in Outlook provided by Outlook/Exchange, so where can the value be sold most? For example, I know a 5-person team in a Fortune 500 that exist solely to make sure this kind of static data is maintained correctly. Any mistake though is gonna need a very strong SLA because it will cost them millions if mistakes happen.<p>Also, your 'About Us' page doesn't work.
