Thanks. </p> https://legacy.forums.gravityhelp.com/topic/calc-days-between-two-dates#post-57446 Wed, 02 May 2012 13:30:04 +0000 kyle 57446@https://legacy.forums.gravityhelp.com/ <p>Ah, sorry. You'll need to use Javascript if it has to happen live. I haven't used it yet, but the <a href="http://momentjs.com/" rel="nofollow">Moment.js</a> library for working with dates in Javascript is probably your friend here. </p> https://legacy.forums.gravityhelp.com/topic/calc-days-between-two-dates#post-57372 Wed, 02 May 2012 09:49:58 +0000 pmwebdev 57372@https://legacy.forums.gravityhelp.com/ <p>Yes - thanks, but how to you display the value of the #Days field after form displayed, but after date field values selected. i.e. but before submitting. Can the #Days field redraw - with the calculation based on the filter function ? (Pardon my lack of knowledge at this stage) Thanks. </p> https://legacy.forums.gravityhelp.com/topic/calc-days-between-two-dates#post-57353 Wed, 02 May 2012 08:17:44 +0000 kyle 57353@https://legacy.forums.gravityhelp.com/ <p>Did you see this post?</p> <p><a href="http://www.gravityhelp.com/forums/topic/start-date-end-date-calculate-of-days-how" rel="nofollow">start date end date - calculate days</a> </p> https://legacy.forums.gravityhelp.com/topic/calc-days-between-two-dates#post-57351 Wed, 02 May 2012 08:15:08 +0000 pmwebdev 57351@https://legacy.forums.gravityhelp.com/ <p>I too have been looking hard for a simple answer to this question - so does anyone have a pre_submission function or other method for calculating the number of days between two selected dates ?</p> <p>Thanks, Peter. </p> https://legacy.forums.gravityhelp.com/topic/calc-days-between-two-dates#post-53661 Wed, 28 Mar 2012 00:14:06 +0000 daveporter 53661@https://legacy.forums.gravityhelp.com/ <p>Is there a way to have a read-only field that displays the number of days between two previously entered dates ?</p> <p>TIA, Dave </p>
