# Customize start and end dates

# Customize start and end dates {#ariaid-title1}

You can configure calendar reports to support the spanning of multi-day events across
calendar cells.

## Before you begin

Role required: dictionary admin or admin.

## About this task

A change request with a Work Start date on Monday and a Work End date on Tuesday is displayed on both days when viewed in a Calendar field. However, when two
custom fields named First Date and Last Date are used, the same behavior doesn't occur.

The code looks for an ending field with the same name as the start date field, except
using the word end instead of start. If the custom fields are My Start Date and My End Date, the system correctly
interprets the meaning of these fields because their names are the same except for
the words start and end.

## Procedure

1. Follow the steps in [Add and customize a
   field in a table](https://www.servicenow.com/docs/access?context=t_CreatingNewFields&version=australia&pubname=australia-platform-administration&ft:locale=en-US).
2. Enter the following values in the form to create the start date span field.

   | Field | Value |
   | Name | <kbd class="ph userinput">Calendar start date span</kbd> |
   | Database column name | <kbd class="ph userinput">u_first_date → u_my_start_date</kbd> |
   | Type | Date |
   |-|-|

   {#t_CustomizeAStartAndEndDate__choicetable_i5h_n5q_y1b}
3. Add another field using the following values for the end date span field.

   | Field | Value |
   | Name | <kbd class="ph userinput">Calendar end date span</kbd> |
   | Database column name | <kbd class="ph userinput">u_last_date → u_my_end_date</kbd> |
   | Type | Date |
   |-|-|
