The plant’s working hours indicate when you can manufacture. Bold uses them to plan operations on each station, to calculate the scheduled time of the OEE, and to know when employees without their own shift work. These hours are part of the plant calendar: each calendar has its own weekly schedule and uses a holiday calendar. Everything without its own calendar uses the general calendar. See Plant calendar for the full model.

​
Before you start

  • To edit calendars and holidays, you need the People.ShiftScheduling.Write permission (HR > Shifts > Edit in the permission profile).
  • To assign a calendar to an area, a line or a station, you need the Production.Workstations.Write permission (Production > Workstations > Edit in the permission profile). To see the Calendar field, you also need People.ShiftScheduling.Read (HR > Shifts > View).
  • Check the company Time zone. The plant’s hours apply in that time zone. See Configure the company.
You can configure the plant calendar with any subscription plan.

​
Define the hours of the whole plant

Path: Control panel > Plant > Calendar > Calendars Open the calendar with the General tag, the first one in the list. Bold creates it with the manufacturing working hours your company had configured. Review them in the Weekly schedule section, which also shows the hours per week, and adjust them if the plant works in other time slots.
1

Add the periods of each day

Each day of the week has its own row. Click Add period and enter the start and end time. You can add several periods to the same day, as long as they do not overlap.
2

Review overnight periods

If a period ends at or before its start time, Bold treats it as ending on the following day and marks it with +1 day. For example, from 22:00 to 06:00.
3

Leave non-working days without periods

A day without periods shows as Closed.
4

Save the weekly schedule

Click Save changes.
Example: in a factory that operates 24 hours, machines are switched on Monday at 06:00 and not switched off until Saturday at 06:00. Add a period from 06:00 to 06:00 from Monday to Friday. Each one shows +1 day.

​
Add the holidays

Path: Control panel > Plant > Calendar > Holidays Each date in the holiday calendar replaces that day’s weekly schedule. The holidays of the whole plant are those of the holiday calendar selected in the general calendar’s Holidays field. Open it from the Holidays tab, or from the general calendar’s page with Edit holidays, next to that field.
1

Choose the day

Go to the month and click the day. The Holiday on dialog opens with the date.
2

Indicate how the plant works that day

Choose Closed if the plant does not work. Choose Special hours and add its periods if it works only some hours, for example from 08:00 to 14:00 on 24 December.
3

Save the holiday

Click Save. The day shows as Closed or Special hours 8:00–14:00, also in the year’s Holidays in list.
To remove a holiday, click the day and choose Remove holiday. Several calendars can use the same holidays: changes affect every calendar that uses them. Employees without their own holiday calendar also follow the holidays of the general calendar.
Bold stores each kind of day as a work day named Closed or Special hours with its hours, and reuses one that already exists. Those work days also appear in People > Work days.

​
Give an area or a machine its own hours

Use a calendar of its own when part of the plant works in other time slots. For example, the Machining area works 24/7 while Assembly works a single shift.
1

Create the calendar

In the Calendars tab, click Create calendar and enter a recognizable name, such as 24/7. In Holidays, choose the holiday calendar it must use; by default, the one of the general calendar. The calendar starts without a schedule.To start from the schedule and holidays of another calendar, click Copy calendar on its row in the list, or Copy on its page, and enter the name of the copy.
2

Adjust its weekly schedule

After you create it, Bold opens the new calendar. Change the periods in Weekly schedule and click Save changes. If you copied it from another one, its schedule is independent: changing it does not affect the original calendar.
3

Assign it to the area, line or station

In Production > Resources, edit the area, line or station. In the Calendar field, click Change calendar and choose the calendar.
4

Review what inherits it

The lines, areas and stations below it without their own calendar start using the new calendar within seconds.
The Calendar field shows the calendar each item uses and where it comes from: To make an area or a station use the calendar of the level above again, click Change calendar and choose Inherit, which shows the calendar it will inherit.
While only one calendar exists, the Change calendar button does not appear on items without their own calendar. Create the second calendar first.

​
Reduced days with another schedule

A holiday date applies equally to all the calendars that use that holiday calendar. If an area with another weekly schedule needs different hours on a reduced day, create a holiday calendar for it with that date and use it in its calendar. For example, if the general calendar works from 08:00 to 14:00 on 24 December and Machining must stop at 22:00, create a holiday calendar in the Holidays tab and add 24 December with Special hours from 00:00 to 22:00. Then open the 24/7 calendar, choose that holiday calendar in Holidays, and click Save changes.

​
Change the general calendar

If another calendar must be the general one, open it in the Calendars tab and click Mark as general. The previous one stops being general, the General tag moves to the new one, and everything without its own calendar starts using it. The general calendar cannot be deleted.

​
Check the result

  • Update open production plans. A plan only picks up schedule changes when you update it.
  • If the general calendar has no working period, Bold cannot create or update production plans.
  • Review OEE by workstation: the scheduled time of each station comes from its calendar, with its holidays.
