OK, I've modified your function, v6o, to avoid using CalendarGetNumDayEvents, and it's working fine when I run it after I've opened the calendar or called OpenCalendar.

function CheckNextSevenDays()
    print("Welcome Screen Guild Page getting calendar information:")
 
    local day = select(3, CalendarGetDate())
    local month = 0 -- calendar use offset by default so 0 is current, -1 previous, +1 is next
    local numDays = select(3, CalendarGetMonth(month))
    for d=1,7 do
        if day > numDays then
            month = month + 1
            day = 1
            numDays = select(3, CalendarGetMonth(month))
        end
        local safety = 100
        local i = 1
        while true do
            local title, hour, minute, calendarType, sequenceType, eventType, texture, modStatus, inviteStatus,
                invitedBy, difficulty, inviteType, sequenceIndex, numSequenceDayss = CalendarGetDayEvent(month, day, i)
            if title then
                if eventType ~= 0 then -- Ignore holidays, call to arms, fishing contests etc.
                    print(inviteStatus.." : "..title.." (type "..eventType..")")
                end
                i = i + 1
            else -- no more events
                break
            end
            
            if safety == 0 then
                print("SAFETY!")
                break
            else
                safety = safety - 1
            end
            day = day + 1
        end
    end
end

I've worked out that CALENDAR_UPDATE_EVENT_LIST fires once its ready, but I'm not sure when to call OpenCalendar, as I want my frame to appear when the player logs in. I've tried PLAYER_ENTERING_WORLD and PLAYER_LOGIN.

Sorry, but I can't work out what your screenshots mean, Xrystal. The second one (with PLAYER_ENTERING_WORLD on relog) seems to be working, but when are you calling OpenCalendar?

Thanks for your help guys,
