Weekend is an optional parameter – a number or a string used to specify the days of the week that are weekend days and are not considered working days. Weekend is a weekend number or string that specifies when weekends occur. Weekend number values indicate the following weekend days:
Number 1 to 7 for two-day weekends and 11 to 17 for one-day weekends.
| Number | Выходные | 
|---|---|
| 1 or omitted | Суббота и воскресенье | 
| 2 | Воскресенье и понедельник | 
| 3 | Понедельник и вторник | 
| 4 | Вторник и среда | 
| 5 | Среда и четверг | 
| 6 | Четверг и пятница | 
| 7 | Пятница и суббота | 
| 11 | Только воскресенье | 
| 12 | Только понедельник | 
| 13 | Только вторник | 
| 14 | Только среда | 
| 15 | Только четверг | 
| 16 | Только пятница | 
| 17 | Только суббота | 
Weekend string provides another way to define the weekly non-working days. It must have seven (7) characters – zeros (0) for working day and ones (1) for non-working day. Each character represents a day of the week, starting with Monday. Only 1 and 0 are valid. “1111111” is an invalid string and should not be used. For example, the weekend string “0000011” defines Saturday and Sunday as non-working days.
Holidays is an optional list of dates that must be counted as non-working days. The list can be given in a cell range.
