Practical details

What this Lucaden tool does

Calendar mode reports complete years, months, and remaining days without treating every month as the same length. Business-day mode counts Monday through Friday and can include or exclude the boundary dates.

Lucaden performs this task in the browser so the source stays under your control. The result is created only after you request it, and nothing is saved to a Lucaden account by this tool.

Questions

About this tool

Are public holidays excluded?

No. Business-day mode excludes weekends only because holiday calendars vary by country, region, and organization.

How are months calculated?

The tool advances complete calendar years and months from the start date, then reports the remaining days.
