# Need a formula for counting information based on date

Hello,

I need a formula that can help me calculate the sum within a column based on date. Not sure if this can be achieved. We are updating information on a weekly basis and I have different rows for the same date. I need a formula to give me the sum based on the date. For example, on 1/17 I will have 6 rows with data that shows hours of worked for each team. This week on Friday we will have new data, so I want the formula to be able to tell me what's my sum for the whole week. If this makes sense, like below, on the Sum column I want the total hours for week ending 1/17 and 1/24 and so forth. I am open to using anything, if anyone has any other suggestions on representing this, please let me know.

Thanks,

• Here is another rather flexible option...

=SUMIFS([Total Hours]:[Total Hours], [Week Ending]:[Week Ending], [Week Ending]@row)

This will sum all of the numbers in the [Total Hours] column that have the same date in the [Week Ending] column as the date in whatever row the formula is on.

• =SUMIF([week ending]:[week ending], WEEKNUMBER(@cell) = WEEKNUMBER(TODAY()), [Total Hours]:[Total Hours])

The formula above should show the sum of week. You can change the "today()" part of the formula to whatever you like to get different results, as I don't think I fully understand how you are trying to format your sheet.

• thanks for sending over the formula, however that changes as the days move along, like Today's date would change tomorrow and I wouldn't be able to tell what was the sum for week of 1/17.

Basically I want to know how many total hours I had on week ending 1/17 and the week after and so forth. I still want that visibility for previous weeks.

• @Jona Gjylameti try this formula, it is very specific to the day.

=SUMIFS({Total hours},{Week ending}, >=DATE(20, 1, 17), {Week ending}, <=DATE(20, 1, 24))

hope this helps.

• @Diana thank you!
