# Modifying and adding calendar report system properties
# Modifying and adding calendar report system properties {#ariaid-title1}
* Release version: Zurich
*
* Updated July 31, 2025
*
*  4 minutes to read
Specify system property values to override Task table highlighting in calendar
events, limit the number of events in a calendar cell, or change the day the calendar week
starts.
## Override Task table field styles for highlighting calendar events {#ariaid-title2}
Highlighting for calendar report events is configured with field styles, which are
defined for a particular table. You can configure whether calendar reports use field styles
from the tables or report sources that they are based on.
### Before you begin
Role required: admin
### About this task
By default, field styles in the Task \[task\] table are applied to calendar reports. If calendar reports are configured to use field styles from their tables or report sources, these field styles override the Task table styles.
Note:
Calendar highlighting only applies to Core UI reports, not to Platform Analytics experience data visualizations.
### Procedure
1. In the filter navigator, enter: sys_properties.list
2. Select the glide.ui.report.extend_calendar_choices property to specify which field styles are used during calendar highlighting.
* If false, calendar reports will use only styles from the Task table when determining options for calendar highlighting. For example, a calendar report on the Change Request \[change_request\] table will only use styles from the Task \[task\] table instead of styles from a the combination of the two tables.
* If True, calendar reports will use field styles from the table that the calendar report is based on.

## Limit the number of events displayed on calendar days {#ariaid-title3}
In calendar reports, you can configure the maximum number of events that appear in
some calendar views.
### Before you begin
Role required: report_admin, admin.
### About this task
When the maximum number of events is exceeded, a + \ link appears, which opens a pop-up window with
additional events. You can also configure the maximum number of events that appear
in this pop-up window. When this maximum is exceeded, a + many link appears, which opens a list of events instead of a pop-up
window.
You can configure these settings for the following calendar views:
* A calendar day when calendar is in month or year view
* The top 'full day' section of a calendar day when a calendar is in day or week view
{#t_ChangeNumberDaysDisplayedCalendar__ul_tq1_3sj_55}
### Procedure
1. In the navigation filter, enter sys_properties.list.
2. Configure the glide.report.calendar.max_events_displayed_per_cell and glide.report.calendar.max_more_events_per_day properties.
3. Click Update.

## Change the day that calendar weeks start on {#ariaid-title4}
By default, weeks for calendar reports start on Sunday. You can add a system property to start weeks on Monday or another day instead.
### Before you begin
Role required: admin
The glide.ui.date_format.first_day_of_week system property modifies the generated date/time value used in the query and sets the start day of the week in the rendered calender.
Note:
glide.ui.filter.first_day_of_week must also be set to the same value as glide.ui.date_format.first_day_of_week for the set day to display properly.
If you change the glide.ui.filter.first_day_of_week property after collecting Performance Analytics score data, you won't be able to view the scores for weekly indicators. To access them, you must [collect scores](https://www.servicenow.com/docs/elYH8j0Wywu3Pw9KQ_BIPg "Performance Analytics uses data collection jobs to collect and clean scores and snapshots. You can also set indicator scores manually.") again.
### Procedure
1. Add the glide.ui.date_format.first_day_of_week system property.
2. Set one of the following integer values.
| Option | Description |
| Start weeks on Sunday | Set Value to 1 |
| Start weeks on Monday | Set Value to 2 |
| Start weeks on Tuesday | Set Value to 3 |
| Start weeks on Wednesday | Set Value to 4 |
| Start weeks on Thursday | Set Value to 5 |
| Start weeks on Friday | Set Value to 6 |
| Start weeks on Saturday | Set Value to 7 |
|-|-|
{#t_ChangeDayCalendarWeeksStartOn__choicetable_mmt_yv3_55}
Note:
Only Sunday and Monday are explicitly supported.
3. Click Submit.
### What to do next
Configure the system property glide.db.week_numbering to specify how weeks are calculated. For more information, see [Customize calendar weeks](https://www.servicenow.com/docs/z3tw0jdjfOCTZ45qIUvsHg#customize-calendar-weeks "Configure a system property to specify how calendar week numbers are determined.").

4. Select Submit.
## Set calendar record limit {#ariaid-title6}
By default, calendar reports save up to 10,000 records. Change this limit by setting

records fetched exceeds this limit, you are prompted to filter the data and run the report
again.
