When you select a date, in all calendar popups the week starts with Sunday, and you would have to allow the week to start on Monday. I don't know if this system is common in the USA, but in Europe the weeks start on Monday. :)! Please support me because when we quickly mark a date we sometimes make mistakes for this reason. I've seen that since 2015 other people have asked for it but it still hasn't changed. ---

Hey Marc, Here’s a solution I came up with. It intercepts Knack’s calls to jQuery datepicker and adds the `firstDay` option that controls which day of the week is displayed first. Simply add the following code to your app’s JS: ```javascript (() => { const jqDatepicker = Knack.$.fn.datepicker; Knack.$.fn.datepicker = function(options) { return jqDatepicker.call(this, { ...options, firstDay: 1, }); }; })(); ``` ---

Actually, a more elegant solution would actually be to just add the following to the top of your JS: ```javascript $.datepicker.setDefaults({ firstDay: 1 }); ``` ---

Thank you very much HMND, I have tested and it works perfectly. Your code is elegant and does what it wants. I’ve been lucky to have your help. ---

By the way, can you think of a way to change the language of the calendar? I would like it in Spanish, because the months and days (acronyms) appear in English. Thanks a lot. ---

To set all relevant datepicker settings to those of the Spanish locale, you can use this: ```javascript // Set first day of week in datepicker to Monday (() => { $.datepicker.regional['es'] = { closeText: 'Cerrar', prevText: '<Ant', nextText: 'Sig>', currentText: 'Hoy', monthNames: ['Enero','Febrero','Marzo','Abril','Mayo','Junio', 'Julio','Agosto','Septiembre','Octubre','Noviembre','Diciembre'], monthNamesShort: ['Ene','Feb','Mar','Abr','May','Jun', 'Jul','Ago','Sep','Oct','Nov','Dic'], dayNames: ['Domingo','Lunes','Martes','Miércoles','Jueves','Viernes','Sábado'], dayNamesShort: ['Dom','Lun','Mar','Mié','Juv','Vie','Sáb'], dayNamesMin: ['Do','Lu','Ma','Mi','Ju','Vi','Sá'], weekHeader: 'Sm', dateFormat: 'dd/mm/yy', firstDay: 1, isRTL: false, showMonthAfterYear: false, yearSuffix: ''}; $.datepicker.setDefaults($.datepicker.regional['es']); })(); ``` Others can use this for their own locales, too. Simply find your locale in the [GitHub repo](https://github.com/jquery/jquery-ui/tree/1-9-stable/ui/i18n) and replace the contents of `$.datepicker.regional` and `$.datepicker.setDefaults` with those from your locale’s file. ---

Hi @Pablo1, it’s still working on my end. Are you using the exact code from the example? Is it having any effect on the date picker, or none at all? ---

upps, sorry, now run perfect. Btw, related to datepicker, do you know any good alternative/solution to admin from/to dates. I mean, select the date range just from one calendar, (different to the date std with the flag" Yes, add options like repeat and end-time to use with a calendar. ".) thanks again. Pablo.
