# “Invalid date provided” error, no Current Month showing

 * [4 months ago](https://wordpress.org/support/topic/invalid-date-provided-error/)
 * On Safari, as well as all browsers on iOS and iPadOS, I’m not seeing the current
   Date on the Calendar view.
 * I noticed the error:
 * [Warning] Error: Invalid date provided: Invalid Date (events-manager.js, line
   4683)
 * I looked at the stack trace:
 * Error: Invalid date provided: Invalid Date
   (anonymous function) — externals.js:
   10:8109pe — externals.js:10:34408(anonymous function) — externals.js:10:33737calendar_month_init—
   calendar.js:142em_calendar_init — calendar.js:246(anonymous function) — calendar.

 * and set a stop at calendar.js:142
 * Interestingly… when I’m stopped there, the current Month *does* display. But 
   when I continue script execution, I get the following error:
 * [Warning] Error: Invalid date provided: Invalid Date — events-manager.js:4682(
   events-manager.js, line 4683)
 * And the Current Month no longer displays

 * More info…
 * code is
 *     ```wp-block-code
       // this bit fixes issues if the supplied text value has a mismatch with the real text value due to localization differences between WP and flatpickrlet month_real_value = monthpicker.val() + '-01';fp.setDate( new Date( month_real_value ) );
       ```
   
 * which results in month_real_value of “February 2026-01”
 * Changed my Month Format to “Y-m” and it’s working.
 * Of course I don’t really want it to say “2025-12” at the top of the calendar
 * I snooped around and found an appropriate value that was independent of the format
   selected.
 * Changing the code above as follows, fixes it (at least for me)
 *     ```wp-block-code
       // this bit fixes issues if the supplied text value has a mismatch with the real text value due to localization differences between WP and flatpickrlet month_real_value = monthpicker[0].getAttribute("value") + '-01';fp.setDate( new Date( month_real_value ) );
       ```
   
 * (Site is now working fine, so no longer a good “broken” example)

 * Gah!!! Nevermind that fix… now the off by one month bug is back.

 * OK, so the problem is that it parses the date in UTC, and in the eastern time
   zone, midnight on the 1st (UTC) is 7:00 pm at the end of the previous month. 
   But, since we only need the Month, just append “-02” and you avoid this problem.
 * let month_real_value = monthpicker[0].getAttribute(“value”) + ‘-02’;
 * That’s working here now (but you can’t use month picker.val() since that uses
   the formatted value and things don’t work well.
 * I assume there’s probably a better way to get year and month out of monthpicker,
   but the code obfuscation makes it a bit difficult to sort that out.

   specify where exactly i can change this value?

 * Search for “this bit fixes” (line 3563 here)
 * replace
 *     ```wp-block-code
       let month_real_value = monthpicker.val() + '-01'; fp.setDate( new Date( month_real_value ) );
       ```
   
 * with:
 *     ```wp-block-code
       fp.setDate( new Date( fp.currentYear, fp.currentMonth, 2 ) );
       ```
   
 * (Note, this is a bit different than the previous solution because I dug a bit
   deeper to find the values from the “proper” place)
