Get Dates

This sub-skill resolves a target date from user arguments and returns all date-related fields needed by planning rituals.

Input

The $ARGUMENTS variable contains the raw date argument:

• •(empty) → today
• •today → today
• •tomorrow → tomorrow
• •monday, tuesday, etc. → next occurrence (including today if matches)
• •next monday, next tuesday, etc. → next occurrence after today
• •YYYY-MM-DD → specific date

Instructions

1. •

   Parse $ARGUMENTS to determine the target date

2. •

   Use macOS date commands to resolve relative dates:

   bash

   # For "tomorrow"
   date -v+1d +"%Y-%m-%d"
   
   # For next weekday (e.g., "monday")
   # Calculate days until next occurrence
   

3. •

   Calculate all date fields for the resolved target date:

   bash

   # Day of week
   date -j -f "%Y-%m-%d" "$TARGET_DATE" +"%A"
   
   # ISO week number
   date -j -f "%Y-%m-%d" "$TARGET_DATE" +"%Y-W%V"
   
   # Month
   date -j -f "%Y-%m-%d" "$TARGET_DATE" +"%Y-%m"
   
   # Quarter
   # Q1: Jan-Mar, Q2: Apr-Jun, Q3: Jul-Sep, Q4: Oct-Dec
   

4. •

   Determine relationship to today:

   • •is_today: target date equals current date
   • •is_future: target date is after current date
   • •is_past: target date is before current date

Output

Return structured JSON:

{
  "target_date": "2026-02-15",
  "day_name": "Sunday",
  "day_short": "Sun",
  "week": "2026-W07",
  "month": "2026-02",
  "month_name": "February",
  "quarter": "2026-Q1",
  "year": "2026",
  "is_today": false,
  "is_future": true,
  "is_past": false,
  "days_from_today": 1
}

Error Cases

• •Invalid date format: Return error with valid format examples
• •Past date: Allow but set is_past: true for caller to handle

Example Resolutions

Week Resolution (for weekly rituals)

When scope=week is passed in arguments or the input contains an ISO week format:

Week Input Formats

• •(empty) → current week
• •last week → previous week
• •YYYY-Www → specific ISO week (e.g., 2026-W07)

Week Calculations

# Get current ISO week
date +"%G-W%V"

# Get week start (Monday) from ISO week
# Use: date command with week calculation

# Get week end (Sunday) from ISO week
# week_end = week_start + 6 days

Extended Output for Weekly Scope

When resolving weeks, include these additional fields:

{
  "target_date": "2026-02-14",
  "day_name": "Saturday",
  "day_short": "Sat",
  "week": "2026-W07",
  "week_start": "2026-02-09",
  "week_end": "2026-02-15",
  "is_current_week": true,
  "is_past_week": false,
  "month": "2026-02",
  "month_name": "February",
  "quarter": "2026-Q1",
  "year": "2026",
  "is_today": false,
  "is_future": true,
  "is_past": false,
  "days_from_today": 1
}

Week Resolution Examples

Week Resolution Logic

1. •If input matches YYYY-Www pattern → use directly
2. •If input is last week → current week minus 1
3. •If scope=week with empty input → current week
4. •Calculate week_start as the Monday of that week
5. •Calculate week_end as the Sunday of that week
