For any year:

Code: Select all

dm-month:march..november
For the current year (2023):

Code: Select all

dm:march..november

Take a look at the Search Functions and you will find the dm-day function and similar, including examples.

Would the following be helpful:

dm-month:march..november dm-day:14..21



or do you need a specific date on March to a specific date in November?
-I don't have an easy way to do this.
You'll have to setup a "datevalue" and then search that.

For example:

14th of March until the 21st November:

addcolumn:a a:=DAY($dm:)+(MONTH($dm:)*32) $a:>=14+(3*32) $a:<=21+(11*32)

where:
14 is the first day.
3 is the first month.
21 is the last day.
11 is the last month.

21 is the last day.
11 is the last month.
Basically, I'm looking to search DST months every year in EDT/EST timezones
1. Winter timezones - first sunday in november to 2nd sunday in march next following year
2. summer timezones - second sunday in march to first sunday in november of the same year

The following might be easier:

FORMATFILETIME($dm:)==FORMATFILETIMEUTC($dm:+(10.5*36000000000))

where 10.5 is your day light savings UTC offset.

This will list files modified during day light savings.

Use != to invert the results.

How does this work because for DST, it depends on EST/EDT,

EST: First Sunday in November to second Sunday in March
EDT: Second Sunday in March to first Sunday in November

This just matches files where the date modified in local time is the same as the date modified in UTC + some offset (10.5 hours in this case).

Date modified is stored in Everything in UTC.
UTC doesn't have daylight savings.
Converting to local time will apply any daylight saving offsets.
The system does this conversion (not Everything).

FORMATFILETIME() will apply daylight saving offsets.
FORMATFILETIMEUTC() does not apply daylight saving offsets.

Adjust the +10.5 hours to match the desired daylight saving offset.
