My favorite international calendar supplement – Holidays 2019 Review

I use this app in combination with Pimp My Calendar. I appreciate the range of countries covered because I want to send holiday cards to overseas friends. It is also useful for professional people and businesses. It can help prevent delays in communications due to unfamiliar national holidays. An app with detailed information on the religious holidays of many should also be considered. This app is well worth the investment for most people and a good Social Studies learning tool for students.
