The descriptions may change so the cells need to be referenced.”

I am trying to use VLookup or QUERY to extract a day and time description based on the current date and time. I thought QUERY may be the best here, but VLOOKUP seems to be the best solution perhaps.

Is it possible to extract the date from between date and time ranges? The descriptions may change frequently so they can't be hardcoded into the formula.

Here is the Google Sheet, which can also be copied. https://docs.google.com/spreadsheets/d/1efQo1t9FJbItYdf1OQJ4vzeG1bUaQ1R0vbFGsgIjzOI/edit?usp=sharing

This was the current formula, which I hoped would extract the correct date and timeslot description

=ARRAYFORMULA(IFERROR(TEXT(A2:A, "dddd ")&VLOOKUP(TIMEVALUE(A2:A), {
 TIMEVALUE(IFERROR(REGEXEXTRACT(TimeDescription!A2:A, "(.*) -"))), TimeDescription!B2:B}, 2, 1)))

回答1:

based on your time data logic try:

=ARRAYFORMULA(IFERROR(TEXT(A2:A, "dddd ")&VLOOKUP(TIMEVALUE(A2:A), {
 TIMEVALUE("00:00"), "Evening";
 TIMEVALUE("07:00"), "Breakfast";
 TIMEVALUE("09:00"), "Morning";
 TIMEVALUE("16:00"), "Daytime";
 TIMEVALUE("20:00"), "Evening"}, 2, 1)))

for non-hardcoded references use:

=ARRAYFORMULA(IFERROR(TEXT(A2:A, "dddd ")&VLOOKUP(TIMEVALUE(A2:A), 
 SORT({TIMEVALUE(REGEXEXTRACT(TimeDescription!A2:A, "(.*) -")), 
 TimeDescription!B2:B}, 1, 1), 2, 1)))

If you have =NOW() in A2, this formula should work without any additional tabs or descriptions...

Apologies, i'd originally Missed the necessity of the day of the week as well. This should work. Again, just with NOW() in A2 and nothing else on the sheet.

=ARRAYFORMULA(JOIN(" ",VLOOKUP(MOD(A2,{7,1}),SORT({{{7;9;16;20}/24;SEQUENCE(7,1,0)},{"Breakfast";"Morning";"Daytime";"Evening";TEXT(SEQUENCE(7,1,0),"dddd")}}),2)))
