== Frequently Asked Questions ==

= How is "Galactday" calculated? =
The "Galactday" is calculated based on the post's publication date, using January 1, 1970 (the Unix Epoch) as a starting point of Galactday 00000.0. It progresses at a rate of 1000 Galactday units per Earth year (using an average of 365.25 days per year to account for leap years).

= Can I change the format or styling of the Galactday? =
Currently, the plugin outputs the Galactday with one decimal place and applies basic inline styling (bold, specific color). For advanced customization, you would need to modify the plugin's PHP code directly, specifically the `$galactday_html` variable within the `slgm_display_galactday_above_content` function.

= Does this plugin affect performance? =
The plugin is very lightweight and performs a simple date calculation. It should have a negligible impact on your website's performance.
