COMMON QUESTIONS
Frequently asked questions
Does the start date count as day one?
No. The count starts with the next eligible day after the start date.
Can I exclude UK bank holidays?
Yes. Choose the relevant UK nation and leave bank holiday exclusion enabled.
Are weekends always excluded?
They are excluded by default, but you can include Saturdays and Sundays if your use case needs them.
Can I use this for contractual or court deadlines?
Use it as a general date tool only. Legal and contractual deadlines can have their own inclusion and holiday rules.
