The getdate method returns a date for a given expression, specifying the date by its position inside a time span which can be of a month or a year.

from bizdays import Calendar
cal = Calendar.load(filename='ANBIMA.cal')

The desired date is the 15th day of May 2002.

The expression is 15th day, year is 2002 and month is 5.

cal.getdate('15th day', 2002, 5)

datetime.date(2002, 5, 15)

If the month is omited the reference is the year of 2002.

cal.getdate('15th day', 2002)

datetime.date(2002, 1, 15)

In the expression 15th day:

• 15th is the position

• day is the desired date that in this case is the current date.

The expression accepts first, second, third, 1st, 2nd, 3rd, [n]th, and last as valid positions and

• day for regular days inside time span

• bizday for business days inside time span

• weekdays: sun, mon, tue, wed, thu, fri, sat

Here it returns the last day and the last business day of 2006.

cal.getdate(['last day', 'last bizday'], 2006)

[datetime.date(2006, 12, 31), datetime.date(2006, 12, 29)]

The first and last Monday of 2006.

cal.getdate(['first mon', 'last mon'], 2006)

[datetime.date(2006, 1, 2), datetime.date(2006, 12, 25)]

A day can be used as a reference, for example, the first Monday before the 30th day of July 2006.

cal.getdate('last mon before 30th day', 2006, 7)

datetime.date(2006, 7, 24)

Or the second business day after the 15th of 2006.

cal.getdate('second bizday after 15th day', 2006)

datetime.date(2006, 1, 17)
