hi all, for a very long time i would like to calculatie time. In a variable (String) i have: 09:30 i would like to substract 75 minutes from it or add hours (whatever). How can i do that? I cannot find any solutions for it, not on github and not on here. Please help! Edit: What was said here:…

Hi Edgar, Where does the 9:30 come from? What are the +/- 75 minutes needed for? Please give an example, maybe I can help you then.

thnx for your reply and that you wanne look into it. the time can excist on multiple reasons. But in this case it is the time when i have to start to work tomorrow. To determine this i use iCalandar to Voice app. But there is no option for to determine when you are done working. The app doesn’t su…

I think there are several possibilities: create a separate appointment in the linked calendar (iCalandar) for the start and the end of working time use the Chronograph App (or similar) to create a timer/countdown over 8 hours and 30 minutes. Start the timer/countdown at the start of work. After th…

Thnx! But that is not what i want, i want to know when i am done working (when i will be free). f.e. i want to know today, when i will be free tomorrow… as long as iCalendar 2 voice doesnt have the option to read the endtime, i only can assume it is 8,5 ours later, but i cannot add this to start ti…

I’m on the road at the moment and can’t try much. I will test something later and get back to you. I may have to sleep on it for a night as well. :wink:

If not done yet, you can also have a look at the official post of the “iCalendar to Voice” app, maybe there are some ideas to solve your problem. [image] iCalendar to Voice by Raymond Brink [not supported - use IcalCalendar] Apps I use it every day to start car warmer. I h…

i asked several times, even on github, but no response. app seems to be dead sadly. thanks you like to check out things. i hope it is possible. like the link i posted before here, it should be possible. but i dont understand what is says. maybe you do?

Performing calculations and writing the calculated value to a variable is not the big problem. To do calculations with a time is not possible in my opinion, at least I don’t know how. In my opinion, only calculations with natural numbers and decimal numbers are possible. Therefore I try to find ano…

It is actualy very simple: if iCalendar to voice appointmen is in 12 hours and appoitment (tag=afspraak) = work then: workstarttime = afspraak (lets say it is 08:00) write notification: your alarmclock is set to 06:45 (- 75 minutes) write variable: workendtime = entime if this works, then i be…

Sorry, I guess I can’t help you. I can’t get the iCalender app to read “Work” (name of the appointment) from the calendar. It always shows only “Test”. Do you? And to calculate the time does not work (in my opinion). Are you able to fill a variable with a time? If so, then probably only a text var…
