• Improved calendar calculations: - Date range is Jan 1, 0001 to Dec 31, 9999. - For any date, the day-of-the-week is shown fully spelled out. - Enter a date as mm.ddyyyy (US, Canada) or dd.mmyyyy (elsewhere), then execute DATE. - A positive input is interpreted as Gregorian, a negative input as Julian. - Convert any date from Gregorian to Julian (and vice versa) by executing DATE. - Enter an integer n, execute DATE to see the date n days later or earlier than the date in Y. If the date in Y is invalid, the last valid date is used. (The current date, if none is available.) Y shows the Julian Day Number of the displayed date. - If Y = 0: 0 DATE returns the current date. n DATE returns the Easter date of the year n (n = 1583 to 4099). j DATE returns the date corresponding to the Julian Day Number j (Gregorian if j is positive, Julian otherwise; j = 1,721,424 to 5,373,484) - Execute ∆DYS to get the number of days from date Y to date X. Y shows the result based on the 30 days/month calendar. Bug Fix: • Stack values didn't show correctly in the register view popup in portrait mode
