Format dates and times according to specific requirements for meeting confirmations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Date/Time Formatting Skill
## Overview
This skill covers formatting dates and times in the specific formats required for meeting confirmation replies, including proper day names, 12-hour AM/PM format, and date formatting.
## Key Concepts
### Required Format Specifications
**Date Format**: `{day_name}, {month} {DD}, {YYYY}`
- Example: `Thursday, January 08, 2026`
- **NOT**: `January 8th, 2026` or `January 8, 2026`
- Two-digit day with leading zero
- Full month name (not abbreviated)
- Full day name (not abbreviated)
**Time Format**: `{HH:MM AM/PM} - {HH:MM AM/PM}`
- Example: `09:00 AM - 10:30 AM`
- Two-digit hour with leading zero
- Two-digit minute with leading zero (never just `9:00 AM`)
- Uppercase AM/PM with space before it
## Code Examples
### Format Date
```python
from datetime import datetime
def format_date(date_obj):
"""Format datetime to 'Thursday, January 08, 2026' format"""
return date_obj.strftime('%A, %B %d, %Y')
# Example
d = datetime(2026, 1, 8)
print(format_date(d)) # Thursday, January 08, 2026
```
### Format Time Range
```python
def format_time(hour, minute, use_am_pm=True):
"""Format single time as 'HH:MM AM/PM'"""

How to install
mdr add cxcscmu/skilllearnbench/datetime-formatting@sha256:73946ddbeeaced13The line at the top of this page pins the label git:20260424.d50cf5a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
