Finance Calendar

Trading-day calendar utilities for financial markets (US, CN, HK).

Overview

This skill provides trading-day-aware scheduling helpers. It helps you:

• Check if a date is a trading day
• Show upcoming trading days
• Sync latest holiday calendar data
• Plan when to schedule tasks (trading-day-aware)

Important: This skill identifies trading days and calculates optimal run times, but does NOT execute scheduled tasks. Use with /loop for actual task scheduling.

Commands

Check Trading Day

/finance-cron check <market> [date]

Check if a date is a trading day for a market.

Example:

/finance-cron check US           # Check today
/finance-cron check CN 2024-12-25  # Check specific date

Show Next Trading Days

/finance-cron next <market> [n]

Show next N trading days for a market.

Example:

/finance-cron next US 5  # Show next 5 US trading days

Sync Calendar

/finance-cron sync [market]

Sync latest trading calendar from data sources.

Example:

/finance-cron sync    # Sync all markets
/finance-cron sync US  # Sync US market only

Plan Task Schedule

/finance-cron add <market> <time> <command>

Plan a trading-day-aware task and get the next execution time.

Note: This command calculates and displays when the task should run, but does NOT execute it. To actually run tasks on schedule, combine with /loop:

Example workflow:

# First, plan the task
/finance-cron add US 09:30 echo "US market opening"
# Output: Next Run: 2024-01-15 (Mon) 09:30

# Then, use /loop for actual scheduling
/loop 0 9 * * 1-5 /finance-cron check US && echo "US market opening"

List Planned Tasks

/finance-cron list

List all planned tasks with their next scheduled times.

Markets

Code	Name	Exchanges	Timezone	Hours
US	US Stock Market	NYSE, NASDAQ	America/New_York	09:30-16:00
CN	China A-Share	SSE, SZSE	Asia/Shanghai	09:30-15:00
HK	Hong Kong	HKEX	Asia/Hong_Kong	09:30-16:00

Integration with /loop

For actual scheduled execution, use /loop with trading day checks:

# Run command only on US trading days at 9:30 AM
/loop 30 9 * * 1-5 /finance-cron check US --quiet && your_command

# The --quiet flag (if implemented) would suppress output for clean scheduling

API for Other Skills

This skill also exports programmatic APIs:

import { isTradingDay, getNextTradingDay, getDueTasks } from 'finance-cron';

// Check if today is a US trading day
const canTrade = isTradingDay('US');

// Get next US trading day
const nextDay = getNextTradingDay('US');

// Get tasks due for execution (for external schedulers)
const dueTasks = getDueTasks();
