# Introduction

This article will show administrators how the system calculates OT during public holidays and rest days.

**Work on Public Holiday**

**Pay for working on a public holiday =**

(12 x Monthly basic rate of pay x Public holidays worked on) / (52 x Average number of work days in a week)

**Not Working on Public Holiday**

**Pay for working on a public holiday =**

(12 x Monthly gross rate of pay x Public holidays falling on a non-work day) / (52 x Average number of work days in a week)

**Working on a Rest Day or Public Holiday which is Rest Day**

**Pay for working a full rest day =**

(12 x monthly basic rate of pay) / (52 x average number of days an employee is required to work in a week) x 2

**Pay for working half a rest day =**

(12 x monthly basic rate of pay) / (52 x average number of days an employee is required to work in a week) x 1
