How do I set the date and time on my EL-1801V calculator?

SOURCE: EL 1801V - how to set time/date?

To change the date, enter the date in MM.DD.YY format, pressing the decimal key between the month and day (will show as a decimal on the display) and the day and year (will show as a dash on the display). Then, press the Time/Date key (the one that looks like a clock and a calendar). The new date will show on the display. Note that if the month is less than 10, you do need to press the 0 (zero) key for the first digit, even though it will not show on the display. To change the time, enter the time in 24-hour HH.MM format, pressing the decimal key between the hour and minute. Then, press the Time/Date key. The new time will show on the display. Note that if the hour is less than 10, you do need to press the 0 (zero) key for the first digit, even though it will not show on the display. Hope this helps! :)
