Tricks and cleverness

o   Entering dates
To indicate your computer's current date, just enter one asterisk (*).
If the year is not specified, Calcad uses the current year. So 27/2 is a valid date.
One period (.) in the field allows you to duplicate the date of the Point 1 tab, two periods (..) allow you to duplicate in this field the date of the Point 2 tab.

o   Entering times
One period (.) in the time field of the Other tab allows you to duplicate the time of the Point 1 tab, two periods (..) allow you to duplicate the time of the Point 2 tab and finally one asterisk (*) allows you to input the time of the computer.

o   Entering angles
You can enter angles either as decimal values separated by a period (for example, for 6.23° enter 6.23), or as degrees, minutes and seconds separated by a degree sign (for example, for: 6° 13' 48" you should enter 6°13°48). You can also mix the two methods: any of the degree, minute, and second values may be decimal. So Calcad accepts the angle 6°12.75 (6° 12' 45") and deduces the value 6.2125°.
