Calendar and Age Calculation Functions |
Chameleon provides built-in Python functions that perform calendar and age-related calculations.
| Function | Description |
|---|---|
| age(birthdate[, date]) | When given a birth date starting with YYYYMMDD (year, month, day), age() returns the years, months and days between this birth date and today's date. These values are all returned as integers. If date is provided, age() returns the years, months and days between the birth date and the date specified by date. date must also start with YYYYMMDD. |
| days_in_month(year, month) | Returns the number of days in the specified month (as an integer). year must be a four-digit number. month must be a number from 1 to 12, with 1 representing January, 2 representing February, and so on. |
| leapyear(year) | Returns true (1) if the year is a leap year, and false (0) if it is not. year must be a four-digit number. |
The following example shows how to use these functions in Python scripts:
from ifware.calendar import *
(years, months, days) = age("19600608", "20090219")
# years is now 48, months is 8, and days is 11
days = days_in_month(2008, 2)
# days is now 29
isleapyear = leapyear(2008)
# isleapyear is now 1 (true)
