Feature request: put in a specific date to count towards

[recklessnl]

First of all - I love using this card! Its great for reminders.

I think it would be really helpful to allow the card to get a date input, and it would count down towards that date. Example use cases:

• Would be great to remind yourself for important dates that aren't set in stone and can change.
• Reminders for renewing SSL certs. The card will countdown toward the day they expire, on a date you set. You can set automations using this card before it expires to remind yourself. Once you renew your certs, you have a new cert with a new expiration date, which might be of a different length compared to the old cert. So you can put in the new date into the check-button-card, click it again, and the card will track it until it's time to renew again.

This would be a great help with keeping track of chores like this that aren't very predictable, this card would be perfect for this.

@Gluwc would you be able to take a look at this? Saw you recently updated this repository again after a while, I think this would be a great addition.

I did merge a PR, but I don't have time to work on this card at the moment unfortunately. Hopefully sometime in the future or maybe someone else can make a PR for this.

FWIW I've used a template sensor to show how many days until a specific date, like so:

days_until_something:
  friendly_name: Something Day
  icon_template: mdi:calendar-check
  value_template: >
    {% set midnight = now().replace(hour=0, minute=0, second=0, microsecond=0).timestamp() %}
    {% set event = '2025-12-31' | as_timestamp %}
    {% set delta = ((event - midnight) // 86400) | int %}
    {% if delta < 0 %}
      {{ -delta }} Days Ago
    {% elif delta == 0 %}
      Today!
    {% elif delta == 1 %}
      Tomorrow
    {% else %}
      In {{ delta }} Days
    {% endif %}

I do like this idea, but maybe this can help in the interim.
