While you can create static sensors or templates to do date-range based automation, I created this so you can easily and quickly create date-range automation on the fly (i.e., turn on Christmas lights if it is between Black Friday and January 6th) or even specific dates within a month (i.e., 1st through the 15th). You can set up four fields and use this blueprint to keep all of your automation together in one place rather than having some as sensors and some as various Py scripts.
The concept is simple, create four number inputs to hold numeric values for the full date (i.e., 20201231), full date without the year (i.e., 1231), the month and the current day. Then in automation use these to determine if the current date falls in between your requirements (i.e., above 1201 and below 1231 indicates any day in December of any year).
Once added, this will run at 5 seconds past midnight each day to calculate the values.
This is my first go at this and it works well in my system, hopefully others will find it useful.
