Would like to automatically update a date field for followups

Rather than using a date field, you could use a formula field. The date functions are documented here, but here’s an example:

Date Contacted (Date)
1/1/2021

Follow-up (Formula)
1/8/2021

Follow-up’s formula:

IF(
    {Date Contacted},
    DATETIME_FORMAT(
        DATEADD({Date Contacted},1, 'weeks'),
        'MM/DD/YYYY'
    ),
    ""
)

If you’d like to use a pattern other than DD/MM/YYYY, date patterns are documented here.

@Zollie thanks! That’s really helpful :slightly_smiling_face:

Just want to ask! I successfully calculate the date. However, airtable said the result isn't present as a date form, so I can not produce a calender accordingly. Would you give some advice!
