This is a sample of holiday check using a local text file in the Lambda function without any use of external databases. This is great for branching to a Holiday or out of office contact flow based on the response. You can use this and queue hours of operation to create a responsive and automated contact center.
You could alternatively load a parameter from AWS Parameter Store with something like the code below:
import boto3
import os
ssm = boto3.client("SSM")
HOLIDAYS = ssm.get_parameter(Name=os.getenv('HOLIDAY_PARAMETER_NAME'))['Parameter']['Value']You would set a lambda function environment variable HOLIDAY_PARAMETER_NAME to the name of the parameter. The parameter would have newline delimited dates in 2020-12-25 formats.
If you want to check ignoring the year you could just compare month and day.
today = str(date.today())[5:]Feel free to mix and match solutions to best enable your contact center!
