Settings - Special Dates

By default, Tricentis Tosca considers all weekdays as working days except for Saturdays, Sundays, and the holidays that you define.

You can define holidays for your test data in the settings under Settings->TBox->Special Dates:

Fixed Holidays
Description	Define holidays that occur every year on a specific date. You can define several holidays, separated by semi-colon. Syntax: <DAY><MONTH>;<DAY><MONTH>;...
Example	0101;0601;0105;1508;2610;0111;2412;2512;2612;3112
