#Excel calculate week number full

To do this we find the first day in january. =ROUNDDOWN(NETDAYS(DATE(YEAR(TODAY()), 1, 1) - WEEKDAY(DATE(YEAR(TODAY()), 1, 1)) + 1, TODAY()) / 7)ДЇirst we need to find the sunday falling on the first week of january. Strategy: Find the number of days between the specified date and the sunday falling on the first week of january, divide the result by 7, and round the result down to get the number of weeks between the dates.

Objective: Find the week number starting from the sunday falling on the first week of january to a specified date. I'll do a quick breakdown of how it works, and how it can be adjusted for different applications. My current path broken down for easier reading- I've probably missed something easy that would uncomplicate it: Certainly though, my solution will become more complex so I'm hoping the community can offer you a cleaner solution. Perhaps as I continue to close my dangling False's some of the issues I see now will resolve themselves. When Jan1 is a Sunday, particularly if it is a Sunday on Smartsheet week 52 (smartsheet 1/1/23), that's a special case- At least for the path I was heading, which is where I stopped. This requires the Smartsheet Adjusted Weeknumbers be offset anywhere from 0 - 2 weeks to match with Outlook. Outlook makes whatever week Jan1 falls in as week1, regardless of what day of the week it is. =IF(WEEKNUMBER([Start + [ADJ > 52, WEEKNUMBER([Start + [ADJ - 52, WEEKNUMBER([Start + [ADJ me, the harder part is

My = IF(WEEKDAY([Start = 1, 1, 0) (This is a Text/Number column) This eliminated having to always check within the formula for Sundays, which on my path saved alot of IFs. I added a helper column called Adj Day to look for Sundays, and added a 1 when it was a Sunday, zero for everything else. I always welcome learning/ building with others.ДЄs I looked at Outlook weeknumbers vs Smartsheet weeknumbers, here's what I observedДЄs you said, Outlook uses Sun as Day 1. You're in luck that Cronk is already weighing in.

The community is full of clever members and I'll shout out to a few that I have seen do very ingenious things specifically with dates- not intentionally leaving anyone out. However making the formula robust enough for any year, at least on the path I started, is complicated. We can easily manage weeknumbers for 2021- which is initially what I thought was needed. I didn't want you to think I had stopped working.
