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.

ah i think i saw my mistake!
the value template line is wrong… oh boy.
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 }}

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” !

Worked perfect
Outside the US, Independence Day depends on the person and when they got divorced! 
I’m really struggling to understand how this is working for you! But if it somehow is, great! I would think {{ now().month in [1,2,3,4,5,10,11,12] }} would exclude Jun-Sept? My thinking is the automation should look like this to only water on Tuesday & Saturday, June 1 to August 31:
description: ""
mode: single
triggers:
- trigger: time
at: "06:00:00"
conditions:
### (when multiple conditions are listed, the default is to 'and' them)
- condition: time
weekday:
- tue
- sat
- condition: template
value_template: "{{ now().month in [6,7,8] }}"
actions:
- action: scene.turn_on
metadata: {}
data: {}
target:
entity_id: scene.water_frontard
I’ve read the Winter sprinkler switch-off - Water Corporation, WA and in my mind, the dates are back-asswards! “The Winter Sprinkler Switch-off runs throughout winter from 1 June to 31 August every year”?? Shouldn’t that read “The Winter Sprinkler Switch-off runs throughout winter from 31 August to 1 June every year”??
I’m totally dumbfounded!
PS. It would help everyone trying to read your automation if you posted it as code rather than as a quote.
hardly…
you’re doing string manipulations, where you should really be entering numbers in those date time templates…
state: >
{{now().month == 7 and now().day == 4}}
would be a better solution
or:
{{(now().month,now().day) == (7,4)}}
please leave ChatGPT out of here
