Turned out to be tricky, but the only method which worked was applying    .valueOf()  to the dates and comparing the numeric representation.

It worked only this way. 

Hi Ruslan,

 

If you want to compare Java dates, you can also use the getTime() method (which returns number of milliseconds since midnight of January 1, 1970) or use the compareTo() method.

 

To easily transform a NotesDateTime object to a Java date you can use the NotesDateTime.toJavaDate() method.

 

 

 Hi, Mark! I wish I had known about conversion earlier. I used to work mostly with LotusScript till now and it's my first time I get into this kind of trouble %-)

Thank you for the advice, guys! You're all really helpful here!
