1 day ago from today is 16 Apr 2025, a Wednesday. Calculating a short time span like 1 days in the past is typically straightforward. For periods under a week, it's a matter of simple backward counting, often doable with just the days of the week. Since today is Thursday, we'll have to adjust for the weekend, if you care about the number of work days. – I generally backtrack using the days of the week for quick reference. Additionally, we’ll need to consider that with 17 days until the end of April, being in the middle of of the month means that 1 day ago will keep us in April and we don’t need to worry about adjusting months or years.
