Linarc's Project Calendar allows General Contractors to establish the site's standard working days and official holidays. These calendar settings are defined at the project level and apply globally to all contractor companies collaborating on the job site.
Defining your non-working days (weekends and holidays) directly influences project logistics and automated calculations across the platform:
- Non-working days are factored into scheduled task durations, dependencies, start/end dates, early start/finish, and late start/finish calculations.
- Holidays and weekends are excluded when calculating actionable deadlines for RFIs, Submittals, Change Orders, and other document workflows.
- Foremen are prevented from scheduling field tasks on designated site holidays and weekends.
- Crew members cannot clock in or submit timecards on non-working days.
Roles:
- General Contractors: Can configure and edit weekly working days and holidays at any time. Note: GCs cannot select holidays as start/end dates or working days for tasks assigned to subcontractors.
- Subcontractors: Have view-only access to the calendar. They cannot edit these settings and must adhere to the working days established by the GC.
Automated Generation & Customization
- Linarc automatically generates a list of national and state public holidays that fall within your project's timeline (from the start date to the estimated end date).
- Review the generated list and manually configure which specific dates the site will remain open or closed based on your company policies.
- Manually add Custom Holidays to account for specific company events, such as a Founder's Day.
Updates for Timeline Changes
If your project duration changes—such as moving to an earlier start date or extending the estimated end date—the system provides the flexibility to update the holiday list to encompass the new timeline. You will need to reset the existing holiday list and generate a new one.
To set up the project calendar
- Ensure you are on the 'Calendar' screen within the 'Project Information' module of the project. If not:
- Click the main menu at the top-left
- Click 'Information' under 'Project' in the menu drop-down.
- Select 'Calendar' on the left.

From this screen, you can:
- Set up Weekly Working days
- Configure General Site Holidays
- Remove Holidays
- Reset the Holiday list and Create a New One
Set up Weekly Working days
- Open the Project Calendar as explained above
The 'Site Working Days' pane displays the designated weekly working days for the project. By default, the system sets Monday through Friday as the working days, but these can be customized to reflect the specific schedule of the project site.
- Click 'Edit' in the 'Site Working Days' pane
- Enable the days you want to set as working days
- Disable the days you want to set as weekly off

- Click 'Save' for your settings to take effect.
Configure General Site Holidays
The 'Holiday List' pane in the 'Project Calendar' screen allows you to view and manage the general holidays that apply to the site, in addition to the weekends.
You can configure two types of site holidays:
- Public Holidays - Allows you to select the national holidays that apply to the site.
- Custom Holidays - Allows you to specify dates apart from public holidays. For example, the 'Founder's Day,' 'Professional Development Day,' or Holidays specific to that state or county.
Set up Public Holidays
- Open the Project Calendar
The list of public holidays that fall within the project duration gets generated.
By default, all holidays are designated as non-working days and are indicated in the 'Site Open' column.
- To set a day as a working day, click the pencil icon in the row of the day, select the 'Site Open' checkbox, and click 'Save.'
- Repeat the process to select more holidays from the public holiday list

Your settings are auto-saved.
Search, Filter, and Sorting Options
- Click the magnifier icon and use the 'Search' box located at the top left to find an entry using any value from the table as search criteria
- Click any column header to sort the rows in ascending or descending order based on that column's data.
- Click the cog wheel icon at the top right to adjust the display density and customize the display and order of the columns
- The options at the top left allow you to filter the entries, create nested groups of entries, and manage personalized and customized views of the table. Use the links below to learn more:
Set up Custom Holidays
In addition to public holidays, you can specify custom holidays for the site depending on your requirements. For example, Founder's Day, days that are holidays in that community but not listed in the public holidays list, etc.
- Open the Project Calendar
- Open the 'Custom Holidays' tab in the 'Holiday List' pane.
- Click 'Add New Row' at the bottom to create a new holiday record
- Enter the details:
- Date - Double-click in the cell and select the date from the calendar
- Holiday - Enter the labe for the holiday
- Site Open - Indicates whether the day is a working day or holiday. By default the day is marked as a holiday. Use the checkbox to mark it as a working day, if required.

- Click 'Save' to save the record
- Repeat the process to add more custom holidays
Your settings are auto-saved.
Remove Holidays
You can remove any holidays you don't need from the list, allowing you to focus only on those you want to declare as official holidays for the site. This helps reduce clutter and improves visibility.
IMPORTANT: Ensure your calendar is fully accurate before proceeding. You can only modify the holiday list until the project schedule is created. Once task timelines are established, the holiday calendar is permanently locked and cannot be edited.
To remove unwanted holidays
- Click the serial number to select a holiday entry.
- Click more than one serial number to select multiple items.

- Click the trashcan icon on the top-right
- Confirm the number of items you selected and click 'OK'
The items are removed from the list.
Note: Once a holiday entry is removed, it cannot be reinstated. If you accidentally delete an entry and wish to re-add it as a holiday, you can include it in the 'Custom Holiday List. Please see Set up Custom Holidays to learn more.
Reset the Holiday list and Create a New One
The Linarc project calendar offers an option to clear the entire holiday list at once. This is particularly useful to update the holiday list when the project timelines are changed or if you wish to reset the holiday calendar configuration and start fresh from scratch.
IMPORTANT: You cannot reset the calendar once the project schedule is active. Ensure your holiday list is finalized before establishing your task timelines, as the reset option will be permanently locked after that point.
To reset the holiday calendar
- Use the 'Select All' checkbox in the Serial Number column header to select all the holidays in the list
- Click the trashcan icon on the top-right
- Confirm the number of items you selected and click 'OK'
The list gets removed.
- Click the 'Generate Public Holidays' button
A new list gets created covering the current timeline of the project. By default, all holidays are designated as non-working days and are indicated in the 'Site Open' column.
- To set a day as a working day, click the pencil icon in the row of the day, select the 'Site Open' checkbox, and click 'Save.'
- Repeat the process to select more holidays from the public holiday list
