C# Question

I have a start date column called

`StartDate`

Here is my code:

`DateTime startDate = new DateTime(StartedDate);`

if (startDate.addDays(7) == DateTime.Today) {

// One week elapsed.

}

Let's say

`startDate`

If, for example, today is 10/7/2016 - the same date as above, so there is 1 week from the start date. How can I determine the number of weeks for dates in the future?

Answer

Try

```
if(DateTime.Now.Subtract(StartDate).TotalDays%7==0)
```

This will give you the modulus of days and equal 0 every 7 days. It will, however, be time sensistve (if StartDate is 2:00PM, days will be 6 until 2:00PM on day 7). If you are only concerned about the day (not time after midnight) use:

```
if(DateTime.Now.Date.Subtract(StartDate.Date).TotalDays%7==0)
```
