To help the last minute taxpayers get the mailed income tax returns postmarked before the April 15 deadline for the filing of their income tax return and the paying of any income taxes that they may owe with the correctly completed income tax return.
For late filers. (Taxes)
April 15th is the last day every year that you can send in your federal income without a penalty. Some post offices are even open until midnight, and as long as your federal return is postmarked April 15th, 23:59 you're good to go.
Post Offices
The plural of Post Office is Post Offices.
Easter was on April 8th that year, so there was no reason to close on the 10th.

Post offices are funded by taxes. You pay taxes, the government takes that money and pays for post offices.
Many post offices have postal workers who are out until midnight or at least "very late" to collect tax filings and get them dated by the 15th. The post office proper will close at 5, 5:30 or 6 p.m. as usual (the actual closing hours vary by office). The U.S. Postal Service knows what time it is, and they will, by and large, have folks out to collect that most important piece of mail and get it post marked with that April 15th post mark. There is 1.800.ASK.USPS (1.800.275.8777) for a recorded message. There is also the post office's web site (and a link is provided). Note that actually getting someone to pick up a phone at this late hour is unlikely, but mail handlers are out there right now.
Post offices are operated by the federal government.
