Sprint S4 Tri-Band running 4.3 MK5. Rooted. I've noticed that no national holidays (4th of July, Thanksgiving, etc) are marked on the google calendar app. A Google search and also searching this very fine forum produces this advice: "Go to the App drawer and run the Calendar app. At the top, select the 'Calendars' box. Then under your Google account, select 'US Holidays". No such options on my phone! I open Calendar, it opens to the current month. The word "Calendar" is at top left, to the right is "Today", and a "+". Touching / long press of "Calendar" does nothing. Sliding sideways does nothing. Quick tap does nothing. "Today" just highlights the current date. "+" brings up "Add event", "Add task", and "Add memo". The Menu button brings up plenty of options, "Calendars" and "Settings" are the most promising, in fact menu > Settings leads to my gmail account the is registered to the phone. But from there, "Display" and "Edit" just leads in circles to screens I've already seen. None of those lead to any option to add "US Holidays". I'm not even trying to sync, import, or share. I just want a usable PERSONAL calendar that along with my personal events shows the major holidays. Help!
