# Dynamic Rules & Scheduling

Pro dynamic rules choose a profile when the **default HTTP rendering API** is requested with `?dynamic=1`. Rules do not alter the static `raw.githubusercontent.com` SVGs as a visitor opens the README.

When rules are enabled for the default profile, the editor generates a dark/light `<picture>` whose sources use `https://gitascii.com/api/USERNAME?dynamic=1&theme=dark|light`. That request evaluates the current rule set and renders or redirects to the selected profile. Explicit named slugs continue to refer to that slug.

## Rule types

| Type | Trigger |
| :- | :- |
| `work_hours` | Configured weekday and time window. |
| `weekend` | Weekend days. |
| `date_range` | Start and end dates. |
| `event` | Named event schedule. |
| `custom` | A custom combination of days, hours, and timezone. |

Higher-priority enabled rules are checked first; the configured fallback profile applies when none match. The simulator in `/pro/profiles` lets you test a date and timezone before enabling a rule.

Dynamic API responses can be cached, so a rule change may not be visible to every client immediately. If you want a stable GitHub-hosted embed instead, use the published `profiles/[slug]/{dark,light}.svg` URLs.
