Calculate with dates

Buckle up
Some examples of calculating time, and converting time (from minutes to hours and v.v)

although again it’s a very nice flow from @Peter_Kawa , perhaps here is a somewhat simpler solution. Only issue is, it works with UTC (since Homey base time is always set to UTC/GMT). [image] new Date().setHours(18,0,0,0) - Date.now() < 5*60*1000; This Condition Expression card will return true when the time is less then 5 minutes before 18u00utc.

Well, you can kind off, but not in the easy ‘formatting’ way: because i didn’t find a all-around solutions independend of locale and timezone. date('DATETIME', null, 'en') You will get a tag, you can use the last number if it’s like this. But if you get this, you will probably get the same result as me: [image] So, the complete solution would be: new Date().setHours(18-Number.parseInt(_.last(date('DATETIME', null, 'en'))),0,0,0) - Date.now() < 15*60*1000; (this is true when less the…

This is guru level I only missed the minutes part of the targeted time, a first wild guess seems to work for 'is true when less than 15 minutes before 18.30h: new Date().setHours(18-Number.parseInt(_.last(date('DATETIME', null, 'en'))),30,0,0) - Date.now() < 15*60*1000;

I share here the power of the BLL card “Set variable to text”.

This means you can add one or more texts and BLL expressions into any text variable, pass the variable to a central flow where you process it with a single BLL card.

This saves (me) several formatting cards in various flows.
