Day of the week:

  - sensor:
    - name: "Day of the week"
      state: "{{ now().strftime('%A') }}"

Today’s date:

  - sensor:
    - name: "Todays date"
      state: "{{ now().strftime('%B %d %Y') }}"

The Time now:

  - sensor:
    - name: "Time now"
      state: "{{ now().strftime('%H:%M') }}"

Sunrise:

  - sensor:
    - name: "Sunrise"
      state:  "{{ as_timestamp(states.sun.sun.attributes.next_rising) | timestamp_custom ('%H:%M') }}"

Sunset:

  - sensor:
    - name: "Sunset"
      state: "{{ as_timestamp(states.sun.sun.attributes.next_setting) | timestamp_custom ('%H:%M') }}"

Sunset sensor that uses frontend date & time settings:

  - sensor:
    - name: "Sunset"
      device_class: timestamp
      state: "{{ states.sun.sun.attributes.next_setting }}"

There is a comprehensive post on handling time here:

The EPIC Time Conversion and Manipulation Thread!.

There are also some template repositories available through HACS or manual installation with very helpful time and date templates:

GitHub - Petro31/easy-time-jinja: Easy Time calculations for Home Assistant templates.
GitHub - TheFes/relative-time-plus: Relative Time Macro with additional options.

Several examples of date-based Template Conditions are shown here.

Most of the available time and date methods and functions come from Python’s datetime library. As such, it can be a great resource for information like strftime() format codes or to learn about methods that may be available and meet your needs, but just aren’t commonly mentioned on these forums.
