I live in an area where the seasons are all vastly different and they all have a different effect on my body. It would be amazing to be able to compare the current 30 day period to the same 30 day period last year.

For example, right now look at 3 April- 3 May 2025 and compare it to 3 April - 3 May 2024. This way if this particular period has higher symptoms experienced compared to 3 March - 3 April because of environmental factors i can also check to see if this is a trend that is on a yearly cycle
