• 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.

• Improved accuracy in extreme cases of y^x with positive, integer x.

• Printer mode ALL is now called TRACE, in agreement with other CuVee Software simulators.
• In TRACE mode, the Easter date function is now clearly marked.
(Reminder: set y = 0, x = desired year (1583–4099), and execute DATE.)
