remarkable so may things to be done in less lines wow you rule!
Any idea why this wouldn’t work? I want it to run if it’s from the 26th through the 31st? It didn’t fire tonight, although I probably have this wrong.
{% set n = now() %} {{ n.month == 10 and 26 >= n.day == 31 }}
or maybe…?
{>25 n.day =31}}
Not sure…
Like this:
{% set n = now() %} {{ n.month == 10 and 26 <= n.day <= 31 }}
Or simply this:
{{ now().month == 10 and 26 <= now().day <= 31 }}

Thanks, I’ll try that. I’m a little confused by the format. In the case of setting lights for Halloween, I only had a few days to figure it out. Thanks again.
hi guys, can anyone help me to set a condition to run an automation only between the months October and April?
I guess this is wrong?
value_template: '{{ now().month >= 10 or now().month <= 4 }}'
many thanks.
Your template is correct if you are using it in a Template Condition like this:
condition:
- condition: template
value_template: '{{ now().month >= 10 or now().month <= 4 }}'
If you wish, you can also do it like this:
condition:
- condition: template
value_template: '{{ now().month in [1,2,3,4,10,11,12] }}'

Thanks so much! it didn’t work but I noticed now I had an extra space at the very beginning. maybe that caused an error…
Hi Taras, the automation is not running. Do you have any idea what could be the problem? Thanks again.
I have no idea because you never posted an automation (just a lone condition). Post the automation so we can all examine it. However, post it in a new topic instead of in this one.
yes of course, i was just about to do that 
Thanks.

Exactly. 
I realize your post is old but I just finished setting up HACS Custom Scheduler Component & Card for my Christmas lighting. It uses From and To dates which I have an automation that will run on January 2nd to change the schedule to the current year.

I have simplified how I am using this as part of my reticulation/water routine. Going to expand the automation for seasonal lights in the near future.
Comments have been included in the YAML code below
I had a similar problem for turning on the christmas lights. Came up with the following solution prior finding this thread ,-). I leave this here to my future self … in case I need to find it in one year.
condition:
- condition: template
alias: "Only during Advent and till two weeks after christmas"
value_template: |-
{{ -14 <= (now().replace(month=12,day=24,hour=20) - now()).days <= 25 }}

If anyone wants to have a bunch of binary sensor entities for common date evaluations, just add these to your templates YAML.

I was inspired by Rak’s solution for X-mas lights. However, it was not resolving to TRUE in the first days of January. So I have changed it to:
alias: Only some days before and after X-mas
condition: template
value_template: >-
{{ (now().month == 1 and now().day < 7) or (now().month == 12 and now().day > 10) }}
5 years gone and still no solution for a date?
I just tried the “time” condition given from hass (without reading the docs: my fault, as it is only comparing the day time and workday and special days, but no dates)
Couldn’t this be enhanced to also look at the date? If 0 is given for year … than it’s not compared? Or duplicate the time condition as “date”?

Hello everyone, I had the same needs, and took your insights to create a pull request to add two new conditions: date and datetime.
This way, we would be able to choose to compare “only the date”, “only the time” or the “date and time” !
Please take a look at it Add date and datetime conditions by Passific · Pull Request #128009 · home-assistant/core · GitHub
