For eg:
Code to get today's date:
$fromMillis($toMillis($now()), '[M01]/[D01]/[Y0001]')
But how to print for 60 calendar days in jsonata? Can anyone please help?`
As suggested in Willy K.'s comment to your question, you can try the following expression:
$fromMillis($toMillis($now()) + 60 * 86400000, '[M01]/[D01]/[Y0001]')
There are 86400000 milliseconds in 24 hours (1 day) and multiplying that by 60 (days) should return a date that is 60 days into the future from the current date.
