Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.
The Date Calci Pro application is used to calculate the difference between two dates, the day and the date. There are three options at the bottom of the screen namely, Diff, Date Calc and Day. Diff allows you to find the number of days between the two dates that you specify. You can find the day corresponding to the specified date and the number of days. The last option helps you in finding what day is a particular date.
You can set default starting date. Count the number of days between the two specified dates. Calculate the date after a after number of days from the starting date. Find the day of a particular date.
