Hi @Kaito_at_Pear - no, you can’t generate a dynamic column/field title with a formula. However, you could create another column which show the date you want if the checkbox is ticked. Something like this:
The formula fields are:
This week: IF(Mon1, DATETIME_FORMAT(TODAY(), 'WW-YYYY'))
Start of Week: IF({This week}, DATETIME_FORMAT(DATETIME_PARSE({This week}, 'WW-YYYY'), 'DD/MM/YYYY 13:00'))
Next Week: IF({Start of Week}, DATEADD({Start of Week}, 1, 'week'))
These could be combined into a single formula field, but I often find it is easy to break this out into “steps” and hide the fields I don’t need to see.
For explanation, “This week” gets the week number of the current week. “Start of week” gets the date of Monday of the current week. “Next week” adds one week to “Start of week” to get the date for next Monday.
If this answers your question, please consider marking it as the "solution". If not post again for more help. Thanks!
