dates

Anyone else have the issue in Reminders where it now thinks every other day you type in is treated as "Today"? For example, you used to be able to say; "Remind me to pick up frangers on Tuesday" and it would highlight the word and let you set tuesday as the reminder. But now it's lost its nut...

So in the screenshot attached here. I would like to collect all working hours that belong to a month into a single cell. soo I want to search for a certain data/month and collect those dates to make a summary for in a single cell belonging to a month. I'm not sure where to start. Thanks. Remy
