Masechta Shekalim is the Tractate that deals with the Budget and Operations of the Beis Hamikdash. The budget counted on revenue supplied from the half-Shekel given by each Jewish man in the world. The fiscal year started on Rosh Chodesh Nissan, so preparing for the budget began in Adar. This is the origin of reading Parshas Shekalim on the Shabbos on or before Rosh Chodesh Adar.
On the fifteenth of Adar, Shushan Purim, collection stations would open, ready to accept the annual poll tax.
Shushan Purim was also the day where all serious planning was put into motion; to fix things up for Pesach.
Roads were fixed. (Imagine Jewish Orange Cone season).
Grave markers that were washed away in the winter rains were fixed or replaced. Mikvaos were repaired.
This is the time to start thinking ahead.
How much time do you need to clean your home?
Create a Google calendar to plan ahead.
If you’re having your car detailed or professionally cleaned, make that appointment now. Time slots fill up, especially in cities with sizable Orthodox populations.
If you host your own Sedarim and Pesach meals, start inviting people now.
Look for a new Haggada. The Jewish bookstores and sites already have their Pesachwares out.
