About lightmy.day

lightmy.day is an answer-first site for everyday date, time, location, and browser questions. The site is built for computed answer pages where the result comes first, followed by enough context to make the answer understandable.

What We Build

The first vertical is holiday countdowns. Each countdown page uses a shared holiday dataset and calendar logic to resolve the next relevant date for the active timezone. The location and user-agent pages do the same kind of work for request context: they show what the browser, hosting platform, and network headers make visible.

Product Principles

• Answer first: Put the date, timezone, location, or browser result before the explanation.
• Computed, not padded: Use data and rules where a direct calculation gives a better answer than a generic article.
• Clear context: Show how the answer was derived when the source matters, especially for timezone and location-sensitive pages.

How It Works

Most pages start from structured data or request metadata. Holiday pages use calendar rules. Location pages use IP-derived headers and geographic timezone lookup. User-agent pages parse the browser identifier sent with the request.

The goal is not to replace detailed reference material. The goal is to answer the specific question quickly and leave the supporting details close by.
