Missionem: In SharePoint Designer workflow, you need to determine if a date field is blank.
Forsit: SPD does not provide a direct method for comparing dates to anything other than a date. You cannot create a condition like this: "If [Date Field] equals blank".
Solutio: Convert the date to a string. Use string comparison to determine if the date is blank.

Notes:

Qui etiam de me passurum, pretium fore aut irritum et flare ad WF runtime vel maybe attollere global temperatus 1/2 Gradus, sed erant illis de vano.

Quæstiones:
1) Cum nullum obtestationis supra, it’s not working because the value of a blank date seems to be "?????" (Credo hic valor est transpositis NULL). Cum mihi propono contentis in filum admodum, it shows up as "?????".
2) Joe – when you wrote "If Field is greater than or equal to Today or Field is less than or equal to Today", do you mean that you can use variables like "Today" in workflows? Si ita, quomodo potestis vos? Ive 'had nullam fortunam experirentur, et ego credidi solum bonis sunt in vacuo possunt.
