As you may have observed, all of the tools under the blog's Calculators category had been down for around two or three days. The reason for this issue was a digital certificate that expired on May 16, 2020.


I've already fixed the issue by using a free digital certificate issuer and all the tools are now back online. However, since it is free, I need to update it regularly to make sure that the tools are functioning every time you visit.

Help me in reaching a wide audience by sharing the articles you find interesting. With this, in the future, I can transfer to a more efficient system.


Apologies for the down time.
