New Plugin: TimeWise-Countdown, an inline deadline countdown

Plugins
1

Dear all,
I wrote a new plugin, mainly for my own use, called TimeWise Countdown. The code is here: Felix Hollederer / TimeWise Countdown · GitLab

As I did not find a form to officially submit my plugin for adding it to Joplin Plugins I will post it here.

And I welcome everyone to share their opinion and valuable feedback.
(As a new member I cannot share multiple links and images, so I will post the readme in a later post)

TimeWise Countdown

TimeWise Countdown is a plugin that continually calculates and displays the time remaining until a specified deadline.

Demo

TimeWise Countdown is a plugin that continually calculates and displays the time remaining until a specified deadline. It allows easy customization and formatting.

Usage

TimeWise Countdown identifies special deadline markers in your text and replaces them with a live countdown. The markers follow this format:

[output](d[DEADLINE]{TEMPLATE})
  • output: The parsed template output
  • DEADLINE: The target time; if this date/time has passed, the plugin shows zeros.
    • Supported deadline formats:
      1. year-month-day:hour-minute (e.g., 2025-12-31:13-45)
      2. year-month-day (e.g., 2025-12-31)
      3. hour-minute (e.g., 13-45)
      4. Short years (less than 100) are interpreted as 20xx. For example, 25-12-31 -> 2025-12-31.
  • TEMPLATE: Specifies how the remaining time should be displayed. Separate tokens with underscores ( _ becomes a space).

Template Tokens

Each letter indicates how to count down:

  • y = Years
  • m = Months
  • w = Weeks
  • d = Days
  • H = Hours
  • M = Minutes

All non-token text (e.g., years, days, minutes) remains literal. For example:

y_years_d_days_M_minutes

could output something like 1 years 9 days 30 minutes.

Examples

  1. Full Date-Time

    [](d[2025-01-10:14-00]{y_years_d_days_H_hours})
    • Suppose today is 2024-01-01 00:00.
    • This might display: [1 years 9 days 14 hours](d[2025-01-10:14-00]{y_years_d_days_H_hours})

  2. Date Only

    [](d[2025-01-10]{m_months_d_days})
    • With a current date of 2024-01-01, you might see: [12 months 9 days](d[2025-01-10]{m_months_d_days}).

  3. Time Only

    [](d[15-30]{H_hours_M_minutes})
    • If it's currently 09:00, it could show: [6 hours 30 minutes](d[15-30]{H_hours_M_minutes}).

  4. Short Year

    [](d[25-01-01]{y_years_m_months})
    • Interpreted as 2025-01-01, so if we're in 2024-01-01, that might be: [1 years 0 months](d[25-01-01]{y_years_m_months}).

  5. Week Calculation

    [](d[2024-02-15]{w_weeks_d_days})
    • If only a few weeks remain until Feb 15, 2024, this might read: [2 weeks 3 days](...).

  6. Past Deadlines

    • If the deadline is in the past, all tokens become zero, e.g.:
    [](d[2023-12-31]{y_years_d_days_H_hours})

    becomes:

    [0 years 0 days 0 hours](d[2023-12-31]{y_years_d_days_H_hours})
