To add a new Bank Holiday on oneHR, click Admin on the oneHR main menu. Within the Admin section, click on Holiday Year & Public Holidays.
You will then be presented with the option to add a new public holiday, along with a list of pre-existing public holidays.
Here you are able to add the title for your Bank Holiday (e.g. Easter Monday), select the date and then click Add.
Once added you will see that this Bank holiday has been shaded out in grey on the Leave Calendar for all employees.
These bank holidays will be deducted from the annual leave entitlements of any employees whose leave allowance is set to include Bank Holidays. You can check how entitlements are set by heading into an employee's profile and checking the Leave Allowance tab.
Here is a guide on updating an employee's leave allowance.
