Hi @onyx808
It looks like you have set the ‘save_format’ of your date picker field to ‘ddmmyy’. Is this correct?
If so, I highly encourage you to change it back to ‘yymmdd’ so that you can use it to better query the DB.
This aside, You can format the date following the code example on this tutorial:
