Automated summary
A date utility that provides current time context, offsets, weekdays, and diary paths to avoid mental date calculations.
Strengths
- Eliminates mental date math errors
- Offers multiple views (day, week, month)
- Handles diary paths with existence checks
Limitations
- No advanced timezone support
- Fixed date format (English)
- Requires Unix environment with bash
Use this skill at session start or whenever you need to reason about dates in your scripts or files.
Avoid it for complex date arithmetic such as business days or timezone differences.
Security analysis
SafeThe skill only runs a designated bash script that outputs date information and checks for diary file existence. No destructive, exfiltrating, or obfuscated actions are present. The script uses safe system commands and the skill does not expose any sensitive data.

From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/date-context-mm8o51nv/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/date-context-mm8o51nv' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/date-context-mm8o51nv/download' --output '.skill-downloads/date-context-mm8o51nv/SKILL.md.part' && mv '.skill-downloads/date-context-mm8o51nv/SKILL.md.part' '.skill-downloads/date-context-mm8o51nv/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
Tools declared by the author (check availability in your agent): Bash(.claude/skills/dates/scripts/date_context.sh:*)
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.
Claude Code
test -f '.skill-downloads/date-context-mm8o51nv/SKILL.md' && test -s '.skill-downloads/date-context-mm8o51nv/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/dates' && cp -R '.skill-downloads/date-context-mm8o51nv' '.claude/skills/dates'OpenSkills
OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.
Official OpenSkills installationopenskills install './.skill-downloads/date-context-mm8o51nv'openskills read 'date-context-mm8o51nv'Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.
For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/date-context-mm8o51nv/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
