There are several filters that can be used to interact with times and dates. This is a list of them:

For example:

{% assign prev_date = '2019-06-20' %}
{% assign new_date = prev_date | advance_months:3 | advance_years:1  %}

Original Date: {{ prev_date | date:"%d/%m/%Y" }}
New Date: {{ new_date | date:"%d/%m/%Y" }}

Another example:

{% assign hour = '10/06/2019 15:45:00' %}
{% assign new_hour = hour | retract_hours:5 | advance_minutes:25 %}

Original Hour: {{ hour | date:'%H:%M' }}
New Hour: {{ new_hour | date:'%H:%M' }}

Comparing with dates

Not all dates are formatted in the same way, as it depends on the kind of variable it is. We can distinguish the following kind of variables and their date format by default:

Input variable with the date attribute

{% input custom.report.date_gm as:date placeholder:"DD/MM/YYYY" %}

will be formatted as dd/mm/yyyy (eg. 14/02/2022).

Local variables

Local variables can be formatted with any date format:

{% assign my_date = "2022-12-31" | date:"%Y" %}

will give 2022 as output.

Period drop dates

The period drop dates are formatted as ‘yyyy-mm-dd’ by default, such as:

{{ period.year_end_date }}

will give 2022-12-31 as output.

Due to different date formats possible, it is advised to always convert any date to the following specific date filter:

date:"%F"

which converts any date to the format yyyy-mm-dd.

🚧

Even if 2 dates of the same kind of variable are compared (eg. inputs with the date attribute), it is a good practise to convert them anyway to this specific date format with the filter %F.
