I have some tasks that where the duration is in days (not workdays).
What formula would I used to calculate a future date and if it lands on a weekend to "round up" the future date to the following Monday (or round down the Friday)

I have a calendar occupying a range A2:AB33. I want to be able to count the number of days (excluding Saturdays and Sundays) between the current day and a specific day in the future (in this case 30th May 2014). I haven't yet found a way of doing this with a worksheet formula.

### Counting down from future date/time to NOW()

Free: Yes
Tags: Excel ›

Good evening and thank you in anticipation for any help offered.
1. I want to be able to add a differing number of hours and minutes to the current date and time and have this displayed as a new date and time in a separate cell. This remains static.
2. I then need to have another cell counting down from the new future date / time to NOW(). Ideally, I would like the countdown to be in hours and minutes rather than days, hours, minutes.
i.e. 01.04.11 19:50 hours + 75 hours 20 minutes to give a new date and time.
I have spent the last two days trying all the time / date solutions I could find on this site, but nothing has worked. I am invariably getting VALUE errors or negative number errors.

### Calculate date

Free: Yes
Tags: Excel ›

I am trying to calculate dates to be used on a construction schedule. Below is what the data looks like:
A1 (task) Start Date Days Completion Date
Roofing 05/05/2011 5 05/12/2011
If the starting date + days do not include a Saturday or Sunday, simply take the starting date and add the number of days. Note that for framing the starting date is 05/03/2011 for 2 days, the starting date is always the first day of the count. If the starting date + days includes a Saturday or Sunday, I do not want to count the weekend days like I have shown for roofing.

### Countdown to Day Script

Free: Yes
Tags: JavaScript › Excel Countdowns

There are basically two types of JavaScript countdown scripts, depending on what you're trying to do. The first type counts down using the time of the visitor's computer, which obviously varies depending on the visitor, and is great for counting down to "relative" events such as Christmas, your friend's birthday etc. The second type counts down using a specific local time (ie: Time in New York), and is great for counting down to "absolute" events where the target date/time is tied to a certain time zone, such as the launch date of a web site, the date/time of the next Solar Eclipse etc.
Dynamic Countdown script belongs to the first type of count down script that lets you count down to relative events of a future date/time. This future date, while the same for everyone, occurs differently depending on the time zone they're in (ie: Christmas, your mom's birthday, April 1st 2015 etc). This script is extremely flexible- you can customize exactly how to display the output, or even specify a custom action to perform at the end of the countdown (ie: go to another page), by passing in your own custom format function.
