Covers South Africa's 12 public holidays. Good Friday and Family Day (Easter Monday) are computed for any year. When a public holiday falls on a Sunday, the following Monday is observed — this is applied automatically.
Formula
Working Days = Weekdays − National public holidays falling on weekdays
Count all Monday–Friday days in the range, then subtract South African national public holidays that fall on those weekdays. Under the Public Holidays Act, if a holiday falls on Sunday, Monday is observed as the public holiday. Holidays falling on Saturday are not substituted.
Worked Example
Scenario: A Johannesburg supplier quotes a 10 working day lead time starting Monday 14 April 2025.
Good Friday (18 April, Friday) and Family Day (21 April, Monday) both fall within the first two weeks — two weekday holidays.
10 working days + 2 Easter holidays (18 + 21 Apr) = 12 weekdays forward
Result: deadline falls on 30 April 2025
The Easter period eliminates both Friday and the following Monday. Any 10-day window starting in mid-April will be extended by these two consecutive losses.
Common Mistakes
- Confusing the Sunday substitute rule. South Africa's Public Holidays Act only provides a Monday substitute when a holiday falls on Sunday — not Saturday. In 2025, National Women's Day (9 August) falls on a Saturday. The Saturday is not a weekday, so no working day is lost, and no Monday substitute is triggered. This differs from some other countries that substitute both Saturday and Sunday holidays.
- Missing Family Day (Easter Monday). South Africa calls Easter Monday "Family Day." Teams from countries where Easter Monday is not a statutory holiday (such as the US) frequently forget this date. Combined with Good Friday, Easter eliminates two consecutive weekdays — Friday and the following Monday.
- Forgetting the Day of Goodwill (26 December). South Africa observes both Christmas Day (25 December) and the Day of Goodwill (26 December) as national public holidays. The Day of Goodwill is equivalent to Boxing Day in the UK and Commonwealth countries. Both days are statutory and eliminate two consecutive working days when they fall on weekdays.

Working days in South Africa: what you need to know
South Africa observes a standard Monday–Friday working week. Working days exclude Saturdays, Sundays, and all 12 national public holidays gazetted under the Public Holidays Act 36 of 1994. This calculator applies the Sunday substitute rule: when a public holiday falls on a Sunday, the following Monday is observed as the public holiday.
South Africa has one of the higher public holiday counts globally — 12 days per year, compared to 8 in England & Wales and 11 in the US. Several SA holidays fall in clusters: Freedom Day (27 Apr) sits close to Workers' Day (1 May), creating bridge-day periods that reduce working days significantly in late April and early May.
For payroll, leave accrual, and contract notice periods, the SA Basic Conditions of Employment Act (BCEA) measures obligations in calendar days for most purposes, but working days apply when determining minimum notice periods for dismissal and when calculating certain leave entitlements.
SA public holidays and planning implications
Late April / early May cluster
Freedom Day (27 Apr) and Workers' Day (1 May) sit 4 calendar days apart. In years where one falls on a Tuesday or Thursday, many SA businesses operate on a reduced working week for the entire period — effectively only 3–4 working days across both weeks.
Heritage Day and December period
Heritage Day (24 Sep) often creates a long weekend. In December, Day of Reconciliation (16 Dec), Christmas (25 Dec), and Day of Goodwill (26 Dec) mean that the period 16–26 December typically contains very few working days — important for payment terms and SLA planning.
Payroll and leave planning
When calculating leave days or minimum notice periods under the BCEA, using working days rather than calendar days produces materially different numbers. This calculator counts only working days, making it suitable for SA leave planning and notice period verification.
Invoice and delivery timelines
SA B2B contracts often specify payment terms in calendar days but logistics deadlines in working days. Net 30 calendar days from a late-April invoice can fall during the May public holiday cluster — use this calculator to identify the real business deadline.
