I'm trying to write a script so that people can input their birthday in a day/ month/ year format and i was wondering if its possible or maybe easier to do it using:

date '+%w' ?
CAL(1)							    BSD General Commands Manual 						    CAL(1)

cal -- displays a calendar SYNOPSIS
cal [-smjy13] [[month] year] DESCRIPTION
Cal displays a simple calendar. If arguments are not specified, the current month is displayed. The options are as follows: -1 Display single month output. (This is the default.) -3 Display prev/current/next month output. -s Display Sunday as the first day of the week. (This is the default.) -m Display Monday as the first day of the week. -j Display Julian dates (days one-based, numbered from January 1). -y Display a calendar for the current year. A single parameter specifies the year (1 - 9999) to be displayed; note the year must be fully specified: ``cal 89'' will not display a calen- dar for 1989. Two parameters denote the month (1 - 12) and year. If no parameters are specified, the current month's calendar is displayed. A year starts on Jan 1. The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd of September. By this time, most countries had recognized the ref- ormation (although a few did not recognize it until the early 1900's.) Ten days following that date were eliminated by the reformation, so the calendar for that month is a bit unusual. HISTORY
A cal command appeared in Version 6 AT&T UNIX. OTHER VERSIONS
Several much more elaborate versions of this program exist, with support for colors, holidays, birthdays, reminders and appointments, etc. For example, try the cal from or GNU gcal. BSD
June 6, 1993 BSD
