Title: Date format validation problem Last modified: September 7, 2020 --- # Date format validation problem * [Olivier](https://wordpress.org/support/users/pumpk1in/) * (@pumpk1in) * [5 years, 9 months ago](https://wordpress.org/support/topic/date-format-validation-problem/) * Hi, * I don’t know exactly since which plugin version this bug occurs. But, that was 100% working when we created the form. * We have this : `` * This is a birthday date. Format dd-mm-yyyy * The form will always say that this is not a correct date format and refuse to send. As I said, it was OK some time ago. * Now, it seems to only accept english formats, like yyyymmdd. * Could you fix that ? * Thanks. * Ps: the form is on the bottom of the linked URL. - This topic was modified 5 years, 9 months ago by [Olivier](https://wordpress.org/support/users/pumpk1in/). * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fdate-format-validation-problem%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ The topic ‘Date format validation problem’ is closed to new replies. * ![](https://ps.w.org/mailin/assets/icon-256x256.png?rev=2993173) * [Brevo - Email, SMS, Web Push, Chat, and more.](https://wordpress.org/plugins/mailin/) * [Frequently Asked Questions](https://wordpress.org/plugins/mailin/#faq) * [Support Threads](https://wordpress.org/support/plugin/mailin/) * [Active Topics](https://wordpress.org/support/plugin/mailin/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/mailin/unresolved/) * [Reviews](https://wordpress.org/support/plugin/mailin/reviews/) * 0 replies * 1 participant * Last reply from: [Olivier](https://wordpress.org/support/users/pumpk1in/) * Last activity: [5 years, 9 months ago](https://wordpress.org/support/topic/date-format-validation-problem/) * Status: not resolved
