Working Day (Business Day)

A working day, or business day, is a day people are normally expected to work - typically Monday to Friday, excluding weekends and public holidays. It is the unit behind deadlines, leave, and delivery estimates.

How it is counted

Start from all calendar days in a range.
Remove weekends (usually Saturday and Sunday).
Subtract public holidays that fall on a weekday.

The result is the working days available for planning.

Why it matters

Deadlines and leave are usually expressed in working days, so an accurate count avoids over-promising.

How Sandtime.io fits

Plan the days, then let Sandtime.io record the hours actually worked on them, so plans and reality line up. Count working days first with the working days calculator.

Working days exclude public holidays, frame annual leave planning, and are the days a timesheet usually covers.

Public Holiday

Official days off recognized by a country's government. Most employees are entitled to paid leave.

Annual Leave

The paid holiday an employee is entitled to each year for rest, with a statutory minimum in most countries (at least four weeks under the EU directive).

Undertime

Hours logged below the daily or weekly goal. Sandtime.io shows undertime as an unfilled progress bar - the gap between what you planned to work and what you tracked.

Timesheet

A record of hours worked by an employee over a specific period. Used for payroll, billing, and compliance.
