I'm puzzled by an error I am coming up against ...
WORKDAY({Send your invoice by}, 10, '01-01-2023, 02-01-2023, 07-04-2023, 10-04-2023, 01-05-2023, 08-05-2023')
WORKDAY({Send your invoice by}, 10, '01-01-2023, 02-01-2023, 07-04-2023, 10-04-2023, 01-05-2023, 08-05-2023, 29-05-2023')​
I don't understand why adding that date breaks the formula, can anyone advise please?

Hi Hairtable. The WORKDAY function asks that your string of holiday dates are ISO formatted. AFAIK, that means YYYY-MM-DD. So, I'm not sure why your original date string is allowed, but I could imagine Airtable allows the MM-DD-YYYY format as well. Your original set can be mistaken for that format even though I'm sure you have it as DD-MM-YYYY. Then, you add 29-05-2023 and it breaks.

That’s really helpful. Huge thanks @augmented
I have reformatted the dates as you suggest, and the error is gone 🙂
