Overview
[edit source]This module calculates the days since the last update stored in Data:LatestUpdate.json and sends to Module:UpdateExcerpt to be displayed by Template:Deadlock Wiki/UpdateExcerpt. It can also be called to calculate the time since any given date, in days.
Examples
[edit source]days_since_date
[edit source]This function can be called to calculate the days passed from a given date, using the format "Month/Day/Year". "Month" has to be in numbers.
For days since January 30 2026:
{{#invoke:LatestUpdate|days_since_date|1|30|2026}}
225
days_since
[edit source]This is an automated function that calculates the days since the latest update stored in Data:LatestUpdate.json.
days_since_text
[edit source]This is an automated function that wraps the "days_since" data in a localized text template to be used by Module:UpdateExcerpt.
