Good to know
Does the first day count?
When counting between two dates, both days count if they are working days. When adding, Zegel starts counting from the day after your start date.
Can I use this for a legal deadline?
As a help, not as advice. Legal deadlines have their own rules; for example, a deadline that ends on a Saturday, Sunday or public holiday moves to the next working day. Check the rule that applies to your deadline.
Does my community’s holiday count?
Not by default: it isn’t a legal public holiday. Choose your community if your employer or school gives that day off.
