Quick answer
SLA deadlines often depend on whether the clock runs during weekends, bank holidays, business hours, or only working days. This calculator helps you sanity-check the date part of that calculation.
Why SLA deadlines go wrong
Teams often count from the wrong trigger date, include weekends by mistake, or forget public holidays. That can make response and resolution reporting look worse than it is, or hide breaches that should be escalated.
Good SLA controls
Define the trigger event, whether day one counts, whether weekends count, whether public holidays count, and what happens outside business hours. Then document the calculation so teams apply it consistently.
Before reporting an SLA breach
Check the trigger time, the agreed calendar, and whether the SLA pauses for weekends, public holidays, or out-of-hours periods.
Use the free calculator
Open the main calculator, choose your start and end dates, select the country, and decide whether public holidays should be excluded.
FAQs
Do SLA business days include weekends?
Usually not, but the SLA wording controls the answer.
Do public holidays pause an SLA?
They can, if the SLA says deadlines are based on working days or excludes public holidays.
Does this calculate business hours?
The site is focused on business days rather than hour-by-hour SLA timers.
