A pollen calendar is used to show the peak pollen times for different types of plant pollens which cause allergic reactions in certain people.^[1][2][3]

In forensics

A pollen calendar can be a very useul tool in forensic science, because it can be used to place the month, or week, or date of death.^[4][5] The use of pollen for criminal investigation purposes is called "Forensic palynology".^[6][7]

However, the use of a pollen calendar to set the date of death should be used with extreme caution, and only by a carefully trained expert witness.^[8] The CSI effect has pressured on some police officers and District Attorneys to provide pollen-based evidence, but "these appear to be of limited use in the forensic context where outcomes are scrutinised in court."^[8]
